                         Programmer's File Editor
                      History of Development Changes
                      ------------------------------

Not all the versions whose numbers appear in the list below have been released
publicly

Items are flagged thus:

  [PFE32] : item is specific to the Windows/NT version
  [PFE16] : item is specific to the Windows 3 version


0.04.009
--------

[PFE16] PFE now can detect it is running under WOW and tailor things
accordingly

Fixed a bug that limited the maximum value of the 'mru-files-shown' ini file
option to 5 instead of the documented 8; also set the minimum value to 0
rather than 3

Added an ini file option 'sound-beep' to suppress all beeps associated with
message boxes

Ctrl+Backspace can now be mapped correctly

Cleared the confusion in handling mapping of Shift+Backspace; for the moment
this has required that Ctrl+Shift+H is no longer mappable

Fixed a bug that caused a print operation to fail when the last line of the
file was printed on the last line of any page

The Edit Goto Line dialog now has a system menu

The OK button in the Edit Goto Line dialog is now enabled only if a line number
has been typed in the Line To Goto edit control

The Edit Goto Line dialog now accepts line numbers preceded by "+" or "-" as
meaning relative to the current line number

Fixed a bug in the Default File/Window Modes dialog that would cause the tab
size to be set as a negative value if soft tabbing was selected

Edit controls in dialogs that accept numeric input are now insensitive to
leading and trailing white space

The Key Mapping dialog now prompts if there are unsaved changes when the Load
button is clicked, and correctly resets the "unsaved changes" flag

Changes to windows made by allowing keys to auto-repeat, and tracking of mouse
selections, should now appear better on slower machines

The "auto-indent" window mode is now respected by the routines that wrap text
as it is being typed

Fixed some bugs in control block chaining that could cause UAEs when closing
some of a large number of open windows and/or files

Installing a printer of an existing type, but connected to a different port,
while PFE is running no longer confuses the Print Setup dialog over which
printer is the default

Printers connected to files by means of a "pathname=" line in the [Ports]
section of win.ini are now handled correctly, and the filename is not corrupted

When text wrapping is active, typing at the end of a line that already extends
past the wrap column now correctly breaks the line at the break point closest
to, and left of, the wrap column

[PFE32] Circumvented a Windows/NT bug that caused a GP fault when the Apply
button was clicked in the Options Default File/Window Modes dialog and some
other dialogs (October 1992 beta only)

The ini file [options] setting "auto-unix" has been renamed "auto-format"

If PFE is exited with the tool bar floating and also hidden, the tool bar is
now drawn correctly the next time it is made visible

The Edit Cut tool bar button, and the key mapped to EditCut, are now correctly
disabled if the current file is marked read-only

PFE now correctly responds when printers are changed via Control Panel.It
no longer records the driver name in its ini file, so that it will not try to
use an obsolete driver after an upgrade

Fixed a bug that caused a parameter validation error in GetWindowLong if
the left button was double clicked in the menu bar and no file was open

Fixed further bugs that would cause looping replacing strings containing
"^n" characters

Fixed a bug causing a parameter validation error in SetWindowText when the
"Remap Key" button of the Options Key Mapping dialog was pressed

[PFE32] Full template functionality is now available. PFE32 now correctly uses
the same file format as PFE16; template files created under earlier versions of
PFE32 will no longer work

[PFE32] The system shutdown options in the "Exit Windows/NT" dialog now
work correctly

[PFE32] It is now possible to run DOS commands and capture output

Fixed a bug that would cause PFE to hang or misbehave while searching if the
text contained characters > 127

The file position in the status bar is now updated correctly after a succesful
search from the Find or Replace dialog

[PFE32] File Insert no longer fails with a "Cannot get file size" message

Fixed a bug that would cause a UAE when performing a template action after
detaching a template file

The File Save All command now saves all open files, and not only altered ones,
if the ini file option 'allow-save-always' is set

A file's save format now cannot be altered if the file is marked as read only

Changing the format a file is saved in via the modes dialog or with the status
bar now marks the file as changed

Added a DDE command EditGotoLine

Added an ini file option 'auto-file-action' to have PFE either create an empty
edit window or show the File Open dialog automatically if started with no file
names on the command line

Files whose first character is a Form Feed (0x0c) character now print correctly

Fixed numerous bugs affecting synchronisation of changes in duplicated windows

File Close now correctly asks if changes should be saved if the current file
is visible in more than one window

[PFE32] File Close now works correctly always

Fixed a bug that would randomly cause the ini file option 'open-maximized' to
be ignored

Fixed a printing bug that would lose the header line giving the file name when
a top margin was selected

[PFE32] Fixed a bug causing a UAE trying to display an empty line that is
not within a selection

[PFE32] Drag and drop of files from File Manager into the PFE window now
correctly opens them

Fixed a bug that could produce "Bad offset" warnings or misplace the caret
when inserting files larger than 8K whose last lines did not end in CRLF or LF

General release on April 18 1993


0.04.008
--------

[PFE32] Fixed a bug that would cause a UAE on clicking the OK box of any font-
selection dialog

Added a 'toolbar-size' option to the ini file to override the automatic sizing
of the tool bar

Removed the confusing Edit|Undo menu option; it will reappear when Undo is
actually implemented

General release on February 1 1993


0.04.007
--------

Fixed a bug that caused DDE errors to occur on startup if PFE was invoked with
file names on the command line

Added a "/k" command line option to allow a key map file to be specified for
loading at startup in place of pfe.key; this option implies "/m"

Instances started with command line options implying multi-instance mode are no
longer erroneously activated by a succeeding start without options

Instances started with options implying multi-instance mode no longer update
the most-recently-used-file list on termination

Added a "/d" option to force the DDE server to be enabled at start-up even if
options implying multi-instance mode are used

Where multiple printers of the same type are configured on different ports, PFE
now shows them all in the print-related dialogs instead of only the first

[PFE32] F1 now correctly activates context-specific help in dialogs

When a search operation is initiated from a Find or Replace dialog, the window
will be redrawn to show the matching string in the second line from the top, to
try to avoid it being hidden by the dialog box

The function names EditIndent, EditUndent, EditLowercaseSelection,
EditUppercaseSelection and EditTransposeCharacters have been changed to be
EditTextIndent, EditTextUndent and so on; key mappings to the old names will
need to be re-instated

Fixed a bug that could put PFE into a loop when using the Window Next command
with all edit windows iconic

The most-recently-used-file list can now be up to 64 names long; names not
shown on the File menu can be selected from a "More Files" dialog

Added a Window Select command, mapped by default to Ctrl+W, to select from many
open windows; the dialog for this replaces the standard MDI "More Windows" dialog

[PFE32] The DDE service name has been changed to be "PFE32", to separate the
services of the Windows/16 and Windows/NT versions

Remedied the omission of the Ctrl+X Ctrl+S combination from the list of keys
that can be mapped

The DDE command EditInsertString has been renamed EditInsert

Fixed bug that would leave a caret in the middle of the Find or Replace dialog
when a match was found

Mappable functions EditRepeatFind and EditRepeatReplace have been renamed
EditRepeatLastFind and EditRepeatLastReplace

Added an Options|ResetFile/WindowModes command to reset the modes of the
current window and the file it shows to those appropriate to the file type

The Printer Font dialog now correctly returns focus to its parent dialog on
close

Limited release to beta testers 20 January 1993


0.04.006
--------

Dialogs now show help if F1 is pressed, as well as with their Help buttons

Fixed a bug introduced in 0.04.005 that caused Ctrl+End to leave the caret
showing beyond the actual end of file

Fixed a bug introduced in 0.04.005 that caused the File Write dialog to be run
twice

Fixed a bug that would leave bitmaps undeleted on exit if ever child windows
were closed by double-clicking in their system menu boxes

[PFE32] Scroll bar elevators now work

[PFE32] Child windows can now be closed by double-clicking in their system menu
boxes

Automatic horizontal scrolling now endeavours to keep the caret as far right in
a window as possible, which should improve the appearance of searches, word
wraps and the like

A command line option "/m" now allows you to force a new instance of PFE to
start even if another is running

Added a "DDE Server" command on the Options menu and equivalent mappable
functions to allow the DDE server system to be turned on and off at will

Added a DDE data item FileName to return the name of the current file

Added a DDE data item WindowTitle to return the title of the current window

Added a DDE command EditFind to perform string searches

Added DDE Poke items OpenFiles and ViewFiles to allow opening of several files
in a single operation over a DDE link

The mechanism for passing command line filenames to previously-running
instances has been rewritten to run asynchronously from the client and pass all
the filenames in one transaction, rather than in separate commands

The mechanism for pasting data over a DDE Poke link has been rewritten to run
asynchronously from the client

Limited release to beta testers 10 January 1993


0.04.005
--------

The status bar has had its intelligence raised, and responds to double-left-
clicks thus: in the line/column area, it starts an Edit Goto Line dialog; in
the Read-Only area it toggles read-only mode; in the Recorder status area it
toggles the recorder on and off; in the Wrap area it toggles line wrap on and
off; in the insert/overwrite area it toggles between the settings. The only way
to banish the status bar is now from the Options menu.

The format a file will be saved in (DOS/Unix) is now shown in the status bar,
and can be altered by double-clicking

The mouse cursor now changes shape to give cues when over the tool bar, over
the status bar, and over a selection

Fixed a bug introduced in 0.04.004 that caused a UAE loading files in UNIX
format

The mouse cursor is now hidden when the user starts typing

Drag-and-drop operations are now disabled completely in read-only files

Fixed a bug that caused a UAE when a drag-and-drop area extended over more than
one line, and the drop target was in the same line as the end point of the
highlight

Fixed a bug that would cause PFE to loop when replacing all occurrences of end-
of-line (^n) characters

Fixed a bug whereby the default file name was not set up in the File Save As
dialog edit control as it should have been

Tool bar buttons are now set correctly if a file is changed from being read-
only to being writable

If a DOS command with output capture action re-uses an existing output window,
the caret is now shown in the correct position relative to the new contents

The Execute DOS Command to Window dialog now has an option to position the
window at the end of the output rather than at the start; this is now the
default behaviour

On startup PFE now checks whether files in the most-recently-used list of files
that are on local hard disks still exist, and silently removes them if not

When a drag-and-drop operation is aborted by pressing ESC, the caret is
returned to the start of the highlighted area and the window redrawn to show it

Added a File Save All command that will save all altered files, store all
altered templates, and save all altered template files

The "Templates" item on the main menu is now "Template" to match every other
reference to it

The help file has been completely rewritten and may now even be useful;
corresponding changes have been made to the Help menu

Dialogs now have Help buttons to give instructions on their use

Dialogs now all have system menu boxes

The File Save command now detects that a window showing DOS command output
has no associated file name, and turns itself into File Save As


0.04.004
--------

A Replace All operation no longer misses out a match in a selection
produced by a previous Replace or FindNext

If the current window is iconic when a Find or a Replace dialog is started,
the window will be restored before the dialog box is shown

Added an ini file option 'allow-save-always' to allow the File|Save menu
item and the corresponding tool bar button to function even if the current
file has not changed

Fixed a bug that erroneously lit the tool bar cut and copy buttons after a
Find operation with 'select matching text' turned off

Fixed a memory manager bug that could cause data corruption or UAEs in
complex circumstances most often seen in replace operations in large files

Added an ini file option 'minimize-on-empty' that iconizes the main window
when the last child window in use is closed

File names shown as the titles of windows are now abbreviated to exclude as
much as possible of the current directory name

Corrected mis-spelling in status bar help line for the 'Repeat DOS Command'
toolbar button

PFE now records its state in the ini file correctly if Windows is shut down
while it is running

When a file name is changed (by File|SaveAs or File|Name) the file and window
modes now change to match those appropriate to the file type in the new name

The status bar INS/OVR flag is now updated correctly if insert mode is turned
on or off using the 'Set Current Modes' dialog

Edit|Text|Indent and Edit|Text|Undent functions now allow the current line, or
all the lines in a selection, to be indented or undented by one tab stop

The Shift+Backspace key combination is now mappable to functions

Automatic text wrapping of lines as they are typed is now implemented

An 'Exit Windows' item has been added to the system menu, permitting Windows to
be closed down in a variety of exciting ways from within PFE.

When the 'Save Changes' message box is shown on exit from the Key Mapping
dialog, focus is now correctly restored to the current edit window

The status bar now shows feedback on the progress of load and save operations

Fixed a bug that caused a spurious blank line to be created whenever a file
being loaded contained a CR-LF byte pair that straddled a storage block
boundary

Auto-indenting is now carried out if a line is split, or if a newline is
inserted, when the caret is in the middle of a line as well as at the end

PFE now has a marginally better knowledge of C syntax and handles brace lineup,
auto-indent and brace matching in a rather more useful way in C language files

Internal re-organisation needed for porting to Windows/NT

Added a way to circumvent a Windows/NT bug that refuses to show fixed-pitch
fonts in the Choose Font dialogs, affecting both the 16- and 32-bit versions;
putting 'fix-font-bug=1' in the [options] section of the ini file will show all
fonts, but attempts to select variable-pitch ones will be rejected [there is no
plan for PFE to support variable pitch fonts]

The File|Name, File|Write and File|Save dialogs now default the file name to
that of the current file, if it has one

The File|Open, File|Name, File|Write and File|Save dialogs now independently
record the filename filter last used, and take that as the default on the next
invocation

A drag and drop operation can now be aborted by pressing ESCAPE before
releasing the left mouse button

Up to five user-defined items may now be added to the Help menu, each one
invoking a specified Windows help file. The menu item Help|WindowsSDK has been
deleted; you should insert an entry in the [help-files] section of the ini file
to access it.

Limited release to beta testers 21 December 1992



0.04.003
--------

The tool bar buttons are now maintained at approximately the same physical
size on all screen resolutions

Changed the way child windows are opened maximized for a better visual
appearance, avoiding a transient restored state

Files can be mailed using MAPI-compliant mail systems

The way that the termination of DOS commands is detected has been changed,
and no longer calls GetModuleUsage with an invalid module handle

The menu item for "Repeat DOS Command", and the "Run DOS Command" toolbar
button, are now disabled while a DOS command is running

Search and Replace operations now use the common dialogs. To be consistent,
"Search" has been changed to "Find" in menus and command names

The file name is now shown in the print Abort dialog, and a faulty call to
SetDlgItemText with an invalid control handle corrected

Fixed a bug that caused a UAE if a strictly empty file was loaded and
a character was typed (this would happen if PFE was used as the editor for
WinQVT/net's POP mailer)

The cursor now changes to an hourglass when cutting or deleting a selection

The format of the [modes] section of the ini file has changed slightly. Soft
tabs are no longer recorded as a -ve tab size, but as a positive value with
a bit flag in the window modes word. Versions of PFE from here on will accept
the old format on startup, but write the new one

Auto-indenting now inserts the relevant number of spaces instead of a single
tab character if the window is set to use soft tabs

Fixed a bug that caused a non-ANSI screen font selected in one session to
be incorrectly selected on subsequent sessions


0.04.002
--------

The "file changed" marker in the status bar has been changed from "C" to "#"
to avoid confusion with language types

Added a standard key mapping Ctrl+Shift+O to invoke EditSplitLine

Fixed random return value from routine that detected a second PFE instance

Characters with ASCII values > 127 are now printed correctly as ANSI characters
rather than as digraphs

Extending a selection generated by a successful search no longer causes a UAE

It is now possible to set the screen font and printer font to non-ANSI as well
as ANSI fonts

The most-recently-used-file list is no longer erroneously appended to the
system menu instead of the File menu if the MDI child is started maximized

Files specified on the command line with names beginning '\' are now handled
correctly

Search-and-replace no longer disregards the 'read-only' status of a file

The filter for "*.exe" files in the Browse sub-dialog of the "Configure
Windows Tools" dialog now works correctly

Fixed a bug whereby some files would not be saved on exit or from a
File|CloseAll operation if some altered files were untitled

General release as the second beta version on 3 November 1992


0.04.001
--------

Improved scrolling behaviour when dragging a selection with a mouse and
fixed several bugs that caused the selection to freeze

Fixed a bug introduced in 0.03.036 that stopped drag-and-drop copy from
working

Fixed some UAEs when scrolling with PageUp when the caret is in the top line
of the screen, with less than one window's worth of lines above it

Fixed inaccurate scrolling down by pages when less than one window's worth
of lines remained below the window and the bottom line of the window was
not one full row in height

If PFE is terminated when the tool bar is a floating window, it will now
restart with the tool bar as a floating window

Making PFE iconic when the tool bar is floating no longer erroneously changes
it to a bar on the right hand border

The way PFE locates the Windows SDK helpfile for the Help|SDK function has been
made more sensible. If the [options] section of the ini file contains a
'sdk-helpfile' key, the name given is used; if not, PFE looks for first
"win31wh.hlp" and then "sdkwin.hlp" on the PATH and uses the first one found.

Limited release to beta testers for validation as the possible beta 2 version
on 19/10/92



0.03.036
--------

When configuring the first tool in the Configure Windows Tools dialog, the
Add button now correctly becomes active as soon as something is typed in
the Command Line edit control

The default mapping of Ctrl-P to File|Print is now shown on the menu

Fixed a bug whereby, if PFE was maximized, made iconic, and closed from the
icon's system menu, it would restart restored rather than maximized

Added an ini file setting "start-maximized" to the [options] section, which
controls whether PFE starts maximized, overriding the saved state at last
closedown

Shift-PgUp and Shift-PgDn no longer cause UAEs or select the wrong sections of
text

Added an ini file [options] setting "track-vertical-thumbtack" that controls
whether PFE scrolls to follow vertical thumbtack dragging

PFE now leaves selected text highlighted after it is copied to the clipboard.
An ini file [options] setting can specify that highlighting is to be removed

Key names in menus and the Key Mapping dialog now use '+' rather than '-'
to link components, to be CUA compliant

The Settings menu has been renamed Options

Corrected a bug in the command line parser that would cause DDE commands and
ini file lines whose last argument was in quotes to be mis-parsed

Added a most-recently-used files list to the File menus

Added a menu option and tool bar action to repeat the last DOS command run

Corrected PgUp and PgDn and scroll bar page moves when caret is not within the
window

The default setting for the 'auto-unix' key in the [options] section of the
ini file is now 1, so that UNIX files will save in UNIX format by default

The Browse Application dialog started from the Browse button in the Configure
Windows Tools now uses a filter showing only "*.exe" files


0.03.035
--------

Improved icons

Some development code that was accidentally left active and caused a UAE
when Ctrl-Z was pressed for an Undo has been removed; undo actions are not
yet supported

Fixed a bug that prevented disabling only a subset of the possible prefix
keys

Dragging the mouse to extend a selection should no longer leave a caret trail
on slower machines

Windows are now scrolled to track movements of the thumbtack in the vertical
scroll bar

All references to "Development Tools" in menus and functions have changed to
use "Windows Tools", to clarify the intended use of the facilities

Details of the actual command line used and working directory are now stored
for all Windows Tools between sessions, and not solely for the last one
used

Limited release to beta testers 05/10/92



0.03.034
--------

When a window is duplicated, the second copy's scroll bars are now set
correctly

Fixed a bug whereby, if a window lost focus when its caret had been scrolled
out of view, the caret would be wrongly placed when the window regained
focus

The tool bar is now disabled when PFE is waiting for the second key of a
two-character command sequence

If the left button is pressed in the tool bar, and the mouse is moved out of
the tool bar before it is released, focus is now correctly restored to the
current window

If the left button is pressed in a tool bar button and the mouse then moved
off the button, the button will return to its down state should the mouse
move back onto it

When dragging the tool bar from a border, the state will now not change
unless the mouse cursor is outside the tool bar when the left button is
released

A 1-pixel gap between the area showing line numbers and the area showing the
text in a window has been eliminated

Ctrl-K can now be used as a prefix key

The prefix keys ESC, Ctrl-B, Ctrl-F, Ctrl-K and Ctrl-X can individually be
enabled and disabled from a sub-dialog of the key mapping dialog. When
disabled as a prefix key, each of them can be mapped to a function as required.
By default they are all disabled, and the hard-coded key mappings are now fully
CUA-compliant. As a result the format of .key files has changed

Pressing TAB when no file is open no longer causes a UAE

Page Down now does nothing if the final line of the file is visible in the
window

Added a File|Name menu item and equivalent DDE command that allows the file name
associated with a window to be changed without writing any data to a disk

The EditPageUp and EditPageDown functions have been redesigned to maintain the
caret in the same screen row, and to keep a memory of the caret column. This
means that a page down followed by a page up returns to exactly the starting
position

Vertical scrolling using the scroll bar now does not move the caret within the
file, but moves it with the text

Selections are no longer removed when the data is scrolled using the vertical
thumbtack

Functions EditShowNextLine, EditShowPreviousLine, EditShowNextPage and
EditShowPreviousPage have been added to give keyboard equivalents of vertical
scroll bar actions

Menu items File|Open, File|New and File|Print are now bound by default to Ctrl-O,
Ctrl-N and Ctrl-P as recommended in the CUA

Pressing a key that is not mapped no longer causes the window to scroll to
show the caret if this is not initially visible



0.03.033
--------

Fixed a bug whereby directories whose names were a single letter or '.' were
not accepted in the Working Directory controls of the DOS Command and Launch
Tool dialogs

Scroll bars no longer respond to the first mouse click if their window is
inactive; the click simply activates the window without disturbing its state

The caret now follows the mouse cursor in a somewhat more friendly fashion
when dragging with the left mouse button down

The File Print dialog now allows line numbering, line wrapping and page header
options to be specified. The corresponding window mode values are now the
default settings for the dialog rather than the active settings

An initialisation file option now allows new windows to be created always
restored; always maximized; or maximized if and only if an existing window is
also maximized. These options can also be made conditional on the main window
being maximized too.

ESCAPE now closes the About dialog box

The vertical elevator is now correctly positioned after a search or a
Window|CentreCaret operation

The ini file and keymap files are now found correctly if the Windows directory
is in a JOINed or mounted directory that appears as the root directory of a
drive

Printer font selection now uses the Font common dialog

Filenames are now correctly set in the document title used by Print Manager
when a file is printed

Window titles for unnamed files, unnamed templates and command output have been
redesigned; the title for an unnamed template and a command output window now
includes a sequence number

PFE no longer beeps to warn of an impossible scroll request (e.g. scrolling
up a line when already in the top line)

The Template|SaveFile and Template|Store menu items no longer both have 'S'
as their hot key

The Template|SaveFile menu item now has an ellipsis to show a dialog will be
run

The File menu has been re-arranged for better CUA compliance

The top and bottom margin checkboxes are no longer confused in the Print
Setup dialog



0.03.032
--------

Changing file and window modes with the Settings|CurrentSettings dialog no
longer erroneously lights the toolbar Cut button

Files can now be loaded and saved in UNIX format, using LF as a line terminator

Clipboard data in excess of 64K is now handled correctly

The File Open and File View dialogs now allow multiple files to be selected

Wildcarded file names can now be given both on the command line and in the
DDE commands FileOpen and FileView

Fixed a bug in which an invalid window handle was passed to IsIconic on
startup, which was trapped by the debugging kernel

Captured output from DOS commands can now be shown in an existing Command
Output window as an alternative to creating a new window

Windows can now be tiled in a custom vertical pattern that maximizes their
width

A new function FileAbandon and corresponding DDE command allows a changed file
to be closed with the changes discarded



0.03.031
--------

Cursor resource memory is now properly freed after the toolbar has been
dragged with the multi-headed-arrow cursor

Text drag-and-drop is now implemented

When a window is duplicated, the copy now correctly inherits the text colours
and language type of the parent

Fixed a bug whereby a non-stock font would not be deleted on termination


0.03.030
--------

If an invalid line number is entered as the target in the Goto Line dialog,
focus is now set back to the control after the error message is shown

Menu items to select the fixed pitch ANSI, OEM and SYSTEM fonts have been added

The "Free Key" and "Free All Keys" buttons in the Key Mapping dialog have been
renamed to "Unmap Key" and "Unmap All"

Selecting Window|Next when all windows are iconic now restores the current
window rather than entering an infinite loop

The Status Bar now uses the Windows variable-pitch ANSI font

Added an Edit|SelectAll menu item to select an entire file

Maximized MDI child windows can now be closed by double-clicking in the
system menu box

The "goto start of file" and "goto end of file" operations are now by default
invoked by Ctrl-Home and Ctrl-End rather than Ctrl-PgUp and Ctrl-PgDn, to
be in line with standard Windows practice

Selected text is now displayed in the correct text and background colours as
set up from the Control Panel

If the current window is set to have a language type of "C", Edit|SelectWord
treats an underscore character as alphanumeric, so that identifiers such as
WM_CREATE can be selected as a single entity

Fixed a nasty memory manager bug that could cause a UAE inserting a newline
after a line deletion in very complicated circumstances to do with the fact
that line control blocks are held in groups of 1024

The vertical thumbtack is now set more sensibly, reflecting the line number
of the line at the top of the window

Positioning within a file containing more than 65535 lines by moving the
vertical thumbtack now works correctly

Tabstop ordering in the Print Setup dialog has been made sensible

Limited release to beta testers 19/08/92


0.03.029
--------

Selecting text with a mouse has been enhanced. Holding SHIFT down while clicking
the left button will select between the caret and the mouse cursor, or will
extend an existing selection

The Window|Widen menu option will now restore iconic or maximized windows before
resizing them

Shift+click on the "Toggle Keyboard Recorder" toolbar button now replays the
keyboard recording

The 'Save File' toolbar button now invokes the TemplateStore function if the
current window contains a template. The button state now correctly reflects the
change state of template windows

The caret now changes size to indicate whether a window is in insert or overwrite
mode

Selecting a word by double-clicking the mouse or using Edit|SelectWord no
longer selects white space to the right of the word

Fixed a bug whereby, after doing a Window|Tile, the wrong window would respond
to keyboard input and scroll bar actions

Fixed a bug which would sometimes cause File|Insert not to close the file that
was inserted



0.03.028
--------

The font used in edit windows may now be selected from all the available
fixed pitch ANSI screen fonts

The 'search' dialog now permits you to specify whether the matching string
is to be selected or not (the default is settable in the ini file). The
dialog also allows you to choose to extend the selection from the initial
caret position to the matching string

All dialogs have been redesigned to use 8pt MS Sans Serif text instead of
10pt System

The algorithm for positioning the caret in the text when the left mouse
button is clicked has been improved: clicking in the left half of a
character cell places the caret to the left of that character, and clicking
in the right half places it to the right

The "Key Mapping" dialog now permits a key to be remapped from one function to
another with a single button click, instead of needing first to free it and
then map it to the target function

The "Free All Keys" button in the "Key Mapping" dialog now requests
confirmation before proceeding



0.03.027
--------

Minor internal changes to make the source compatible with MSC 7.0

The Edit|Text|Uppercase and Edit|Text|Lowercase functions now correctly
mark the file as being changed. They also produce an error if used
on a read-only file. Both now handle characters with ASCII codes > 127
properly; note, though, that neither these, nor anything else in PFE,
will work with Kanji or other languages using 2-byte codes



0.03.026
--------

Altered files can now be saved to disk automatically before running a
DOS command or launching an application or a development tool

The details of the last-used DOS command, application or development tool
are now remembered between PFE sessions. The details of the last used
development tool are also shown as the default each time the dialog is
started

The Run DOS Command dialog box now has a Browse button



0.03.025
--------

Extra functions are now available from the toolbar by using the SHIFT and
CONTROL keys in combination with the left mouse button. See the help file
for details.

The "Window" menu item on the menu bar has been moved to be the last apart
from "Help", to match the standard menu layout for MDI applications

Windows may now be set to use "soft tabs": tabs will be inserted
as an appropriate number of spaces rather than as single 0x09 characters

The "Insert Template" toolbar button is now correctly set as template files
are attached and detached

The TemplateInsert, TemplateEdit, TemplateStore and TemplateStoreAs functions
no longer cause UAEs if no template file is attached

Files that have the "read only" attribute set are opened in read-only mode,
regardless of the "read only" button state in the File Open dialog

Characters with ASCII codes from 128-255 can now be inserted from the
keyboard


0.03.024
--------

Many of the functions shown in the Key Mapping dialog, and the
equivalent DDE commands, have been renamed. They now correspond better
to the menus where they are held (or would be held)

A bug whereby a DDE Poke operation received DDE_FACK on a fail and
DDE_FNOTPROCESSED on successful termination has been cleared

A successful search now sets the toolbar cut and paste buttons correctly

Several new DDE commands and enquiries added

The syntax of the DDE commands CaretLeft(), CaretLeftWord(), CaretRight()
and CaretRightWord() is now changed so that each takes two mandatory
arguments. The first is the count of the number of characters or words
to move, and the second is 1 to extend a selection and 0 not to do so

To avoid confusion over what it is, the support module PFEDOS.EXE, which
is used by PFE to handle output redirection in DOS commands, has been renamed
$PFEDOS.EXE, which hopefully looks less like a DOS version of PFE. The
associated PIF file is now called $PFEDOS.PIF to match

Using selection-extend keys like Shift-Left after marking a selection with
the mouse now has the desired effect. Other minor bugs when moving the
caret with Shift down to extend selection have been cleared

Caret movement keys can now be remapped. This has required an incompatible
change in the format of key mapping files, so that files saved with
earlier releases of PFE cannot be used

The semantics of the default PgUp and PgDn mapping is slightly altered; if
line 1 is at the top of the window, PgUp moves to the start of the file, and
if the last line is at the top of the window, PdDn moves to the end of file.

Shift-PgUp and Shift-PgDn are now mapped to page up/down moves that extend
the selection

To be compatible with standard MDI practice, Shift-F4 now maps to
WindowTile by default, and Shift-F5 to WindowCascade. TemplateInsertMarker
has moved to F6, and CaretCentre to Ctrl-F5

The Goto Line dialog has been enhanced to allow optional extending of
a selection

^T is now accepted as meaning TAB in a search or replace string, as well
as ^t



0.03.020
--------

Released as the Beta 1 version of PFE 28/07/92



------------------------------------------------------------------------------

Reported bugs that have not yet been cleared
--------------------------------------------

The toolbar paste button is not updated correctly if another application is
activated and changes the clipboard contents

If the user tries to save an un-named template, calling it by the same name as
an existing one, and presses CANCEL in response to the confirmation prompt,
the template window is nevertheless given that name

When a selection ends with the cursor at the left of an empty line, the
display code draws a half-cell highlight on that line erroneously

Duplicate windows should have ":sequencenumber" appended to their titles

There is no way to insert special characters such as ESCAPE into a file

Double-click to the right of a line, or in the right-hand half of the last
character in a line, should select the word to the left of the mouse cursor

With text like "point.x = something", double clicking on the right hand side of
the 'x' or left side of the following space uses '.' as a word delimiter when
extending the selection left. This is inconsistent with how extensions right
work, or when the '.' is followed by more than one character

The various "modes" dialogs show error messages when invalid file types are
given, but add them to the list anyway

When the last screen of a file is visible, a PageDown action should take the
caret to the end of the file; similarly for PageUp in the first screen of the
file

A DOS-command-with-capture operation sometimes seems to ignore the specified
working directory and runs the command in the Windows directory

The File Open dialogs should show deeper filter lists; the Microsoft default
depth of 3 lines is pathetic

When a child window exists and is maximised, pressing the first character of a
two-character command sequence grays all the menu bar items, instead of leaving
just the Help menu active

The File Write dialog does not allow Unix format to be specified

Vertical scroll bar handling when the end of a file is visible needs to be
improved

[PFE32] When loading a file, the line count progress area of the status bar
sometimes is cleared to white momentarily

[PFE16] It is not possible to run DOS commands with output capture when PFE is
run in the Win16 subsystem of Windows/NT

Automatic horizontal scrolling can still sometimes fail to position the caret
optimally as far right as possible in a window

The Load Key Mapping dialog does not have a Help button, nor response to F1

After a forward search locates a match, a reverse search on the same string
will locate the same match again

Any line where the number of characters times the width of a character in
pixels exceeds 32K will not get drawn correctly in many cases

Some parts of PFE still impose a limit of 1024 characters in a line; for
safety, do not operate with lines longer than this

Text wrap does not occur unless typing at the end of a line

Under Windows/NT and WOW, it takes 2 double clicks in the system menu box of
maximized MDI children to close them (Microsoft believe this is due to a bug
in Windows/NT)

Font characters that occupy the full width of a cell (e.g. "V" in 8pt Courier
New) may leave a single dot behind when moved by an insert to their left

It is not possible to include quotes in a DOS command whose output is to be
captured

PFE does not disregard a click in a child window if another app is current

[PFE32] The File Save As dialog does not show a Network button

[PFE32] The File Open dialog has no Read Only checkbox

Vertical scroll bars are not updated in duplicated windows showing a file when
the current window is changed

[PFE32] When an application is launched with the Execute Launch Windows Tool
or Execute Launch Application commands, and the application subsequently
starts one of the common File Open dialogs, the directory shown will be
the directory that the original PFE application is running in, not the one
that was specified in the dialog and actually is the current dialog. This
appears to be a bug in the March beta code for Windows/NT

There is no way to specify a Form Feed character in the Find and Replace
dialogs

-------------------------------------------------------------------------------

Reported bugs that cannot be duplicated
---------------------------------------

[A number of bugs seem to occur on some systems, but cannot be made to appear
 on my development system. If you can supply insights or evidence, please get
 in touch!]

Loading a file containing control characters causes either a UAE or a locked
system

On a networked machine, setting a ProgMan PFE icon to start in C:\ causes a
"network error" message

Clicking on a file name in the list of the Open Existing File dialog does not
move the file name to the edit control on systems running with Italian language
drivers (probably a Windows bug)

Current directory is lost if the File Open dialogs change drives.

With no mouse present, selecting Apply and then Save in the "Default File Modes"
dialog freezes PFE until it's reactivated from Task Manager

With a 1024x768 screen driver, the status bar is clipped on the left side, and
it's not possible to position the cursor to the furthest left side of a
maximized text window

On some systems, the two rightmost pixel columns of toolbar bitmaps are not
drawn the first time the bitmaps are shown

UAE when file is dropped from File Manager and PFE is an icon

Share Violations when the work file holding output from a DOS command is opened

All text windows are cleared and redrawn every time PFE is given control after
using another application

Garbled printer output sending to a printer on a Pathworks network


-------------------------------------------------------------------------------

Things To Be Done
-----------------

[This list details features that are intended to appear in the version 1 full
 release. Depending on many factors it may not be possible to implement all of
 the items here for that release - but they should all appear in due course]

Implement Undo

Abolish restrictions on line length and make horizontal scroll bar handling
sensitive to the actual data visible

Add ability to define multiple keyboard macros, with load and save

Improve intelligence of text redrawing to avoid flicker in overstrike mode
and when updating the position in the status bar

Implement double-click-and-drag to extend selection by words

Allow search on regular expressions

Implement paragraph reformatting

Implement save-with-backup and periodic-auto-save features

Record tool bar actions in keyboard macros

Make the line number area resizable by dragging the left border

Provide visual feedback when dragging the tool bar about

Ini file option to allow PageUp/PageDown to work in units of half a window

Allow current file name to automatically be substituted in DOS commands

Use the selected text as the default search string when searching

When a file is renamed by File|Name, PFE should check on saving whether the
file exists, and prompt for confirmation if it does

Remember position of floating toolbar between sessions

When dragging-and-dropping, use Shift down to force a copy regardless of the
ini file settings regarding control key usage

User customisable Execute menu items

Provide way to generate a list of current key mappings into an edit window

Edit|Revert command to revert file to last disk copy

Add support for Macintosh-format files using CR as a line terminator

Add option to ensure that the last of a file is always terminated with
CRLF when it is saved; and to optionally force a blank line to exist at the end

Template Insert should remember the last template inserted and set that as
the default
