                           EasyCASE version 1.7

EasyCASE version 1.70 fixes the following bugs and enhances several functions
as follows. EasyCASE v1.7 is a release which combines all of the maintenance
releases of EasyCASE v1.61 through 1.69 into a single update.

v1.61  11/24/89

a. Re-wrote the HP LaserJet drivers so that less resident memory in the LaserJet
printer is used allowing more complex charts to be printed at 300dpi on HP
LaserJets equipped with only 512K of memory. However, depending on the complexity
of a chart, it is still quite possible that it may become impossible to print
out an entire page at 300 dpi resolution. This is a limitation imposed by the
amount of memory present in the printer and the way complex images are stored,
it is NOT caused by EasyCASE Plus. To guarantee printing of complex images at
300 dpi, you need 1 Mbyte of memory.

b. Fixed a bug which was causing improper printing of images at 100dpi in
Landscape paper orientation on LaserJet printers.

c. Added support for printing on LaserJets at 75dpi, though with a slight
descrease in the number of symbols which can fit on the page horizontally and
vertically.

d. Removed the LASERJET and DESKJET options from the printer selection menu
and replaced them with HPLJ @ 75dpi and HPLJ @ 100dpi. DeskJet printers ARE
LaserJet (HPLJ) compatible so you should select the appropriate HPLJ @ xxx dpi
driver if you want to print on a DeskJet or DeskJet Plus.

e. Fixed a bug which would cause endless beeping and lockup until the Escape
key is pressed when selecting, under certain conditions, the (double ended)
arrowheads option from the main menu or selecting a flow to change the number
of arrowheads on.

f. Added a new option to the #Arrowheads option dialog box. This option is only
enabled for ERDs and enables you to draw an Association with a SINGLE
arrowhead at the SOURCE end and a DOUBLE arrowhead at the DESTINATION end of
the connection to represent, for example, one-to-many relationships. If you
need a double arrow at the source and a single arrow at the destination, either
draw the association connection in the opposite direction or select the option
to change its direction.

g. Added two more options to the Export menu to provide Microsoft Windows v2.03
and PC Paintbrush files at 150 dpi resolution. The other options produce images
at 90 dpi. The 150 dpi image is produced quite quickly but takes a lot longer to
load into PageMaker, Designer, Ventura etc. and is larger than a normal page and
hence has to be scaled to fit. This results in a slight reduction in quality but
is still much better than the 90dpi image quality. Also, because the image does
now consist of a lot more points, you are more likely to get an out-of-memory
error when running applications under Microsft Windows when loading these 150dpi
images into Windows applications such as PageMaker. The 150dpi image has NOT yet
been tested with WordPerfect or Word v5, Ventura or Manuscript. The 90dpi images
HAVE been tested with those products.

v1.62  10/1/89

a. Fixed a bug which would cause the program to 'hang' with an error #5, and
possibly also an error #11, if an attempt was made to Save a chart file to a
project directory specification, together with that of the filename and
extension, to be saved exceeded 40 characters. This has been re-implemented to
save a chart file in the default project directory only. Any path specification
input will be ignored so as to avoid the error and also 'encourage' you to keep
all your project chart files in the same project directory.

b. Fixed a bug which could potentially cause a chart file created by earlier
versions of EasyCASE to cause problems when saved and subsequently re-loaded.

c. Improved the Zoom chart feature to simplify navigating around a large chart.
While in the Zoom=4 (quarter size) mode, selecting Zoom=1 (actual size) mode,
you will be prompted to select an area of the chart to zoom out to. If you
press and hold the left mouse button, a yellow square will appear on screen,
top left corner of which will be located coincident with the mouse pointer. If
you then drag the mouse pointer across the screen (left mouse button still held
down), the rectangle will move also. When you have encompassed the area of the
chart you wish to appear actual size in the chart window, release the left mouse
button. Note that this mechanism currently only applies when moving from zoom=4
to zoom=1 modes.

d. Changed the number of vertical rows printed on a page when printing to Epson
LQ and compatible printers to prevent the bottom symbol row overflowing the
paper perforation and ejecting excess pages. You now can print 13 rows instead
of 14 previously available on this printer type.

e. Can now start EasyCASE pointing to a project directory using the DOS
abbreviated directory specification '..' without the need to also supply a
chart name or type. For example, if EasyCASE is installed in directory
C:\BIN\CASE\EASYCASE and your project files reside in directory C:\BIN\CASE\PROJECT
you can now start EasyCASE from its directory for this project by entering the
following command line - EASYCASE ..\PROJECT.

f. Chart type now correctly appears at top left of screen if EasyCASE is
started without specifying a chart type on the command line.

g. Fixed a bug which would cause loss or duplication of an object label when
Label Object option chosen from menu, object selected, label moved and chart
scrolled prior to final label placement.

v1.63  10/4/89

a. Chart type extension correctly to 'New' filename whenever EasyCASE is
started without starting without a chart filename specified on the command line.
Similarly if started without specifiying a chart type on the command line.

b. Symbol type selection now repeatable when running EasyCASE on a Hercules
graphics card. If the previous menu option selected was SYMBOLS then clicking
the left mouse button inside the chart window will place another of the
previously selected symbol at the mouse pointer position.

c. Fixed a number of bugs relating to the handling of the mouse pointer,
highlighting and input box text attributes when running EasyCASE on the
Hercules graphics card. Mouse pointer no longer lost when over the background
of dialog boxes.

d. Relocated several dialog boxes to center them on screen.

e. Fixed a bug which would cause inability to select a zoom mode if a previous
chart operation was cancelled.

v1.64  10/7/89

a. Re-wrote the Epson LQ Printer driver to prevent possible occurrences of an
Error #14 message when attempting to print on wide paper with a large chart
loaded.

b. Fixed a bug which resulted in a 'File Not Found in module DRAW' after
selecting the NEC/Okidata printer option. Renamed this option to Okidata 393
Series of printers which are Epson LQ compatible 24 pin printers.

c. Modified the dBASE III Plus Export so that ERD connections with one or two
arrowheads at one end only of a connection are identified as 'One-to-Many'
relationships, connections with one arrowhead at one end and two at the other
are also 'One-to-Many' relationships and connections with one or two arrowheads
at both ends are 'Many-to-Many'.

v1.65  10/17/89

a. Fixed a problem in EasyCASE Plus which could result in the mouse pointer
breaking up, in Hercules graphics mode, after returning from the Editor
accessible via the 'Down' option for child text files.

b. Fixed a problem which would cause a page to be ejected from the printer
connected to LPT1: if a print to FILE job was prematurely terminated by
pressing the Escape key and selecting Yes to abort the print.

v1.66  10/29/89

a. Fixed a problem which would result in 'garbage' text labels being printed
when printing a chart, in Hercules graphics mode, to an Epson LQ printer.

b. Fixed a problem which would generate a 'Print Error #5' message when
attempting to print to the 'PRN:' device. Output to PRN: is directed to LPT1:.

c. Fixed a problem which would result in a system crash on attempting to return
from the DOS Shell in Hercules graphics mode.

d. Fixed a problem which would cause loss of menu colors after returning from
the DOS shell in EGA Color mode.

e. Fixed a problem which would result in 43 lines of text in the DOS Shell.

v1.67  11/2/89

a. Fixed a number of problems which caused charts to plot incorrectly on HP7475A
Plotters in Portrait and Landscape orientation on A- and B-size paper when
plotting to a device port or to a file. Problems included reversing on chart
symbols and text horizontally and vertically, blank lines between character
rows and clipping.

b. Fixed a problem which could result in an Error #10 when re-exporting a chart
file in dBASE format.

c. Label text box is brought up before the Identifier selection dialog box when
auto label and autoidentify selected.

d. Area selection box no longer destroys menu text when moved around to select
which area of the chart to zoom in to when changing from zoom=4 to zoom=1. Also
zoom level selection box shadow removed to prevent corruption.

e. Chart offset restored correctly when returning from Print Preview.

f. Split/Merge (DFDs & TRGs) label placed correctly when in zoom modes.

g. Fixed a problem which could result in an incorrect number of arrowheads
being selected for interface or connecting flows depending on the current
default number.

h. Fixed a problem which could result in the wrong label being selected and pla
ced at the top, left hand corner of the chart when a new object is placed and
newly identified with auto identify mode selected.

v1.28  1/90

a. Improper chart file closure resulted if an error in the chart file was
discovered during a load. Open file could be corrupted when going to plot or
exporting under certain circumstances.

b. When Plotting to a COM: Port, label lines would over-write due to lack of a
line feed after a carriage return. Plotting to an LPT: port was OK.

c. The size of the selection box when exporting a chart fragment in Paint file
format at 150dpi was inaccurate. Also, less rows were exported at 150dpi than
at 90dpi. 14 rows are now exported in both cases. The selection box now
accurately bounds the chart fragment exported.

d. An error occurred preventing use of the Microsoft Windows Paint v1.01 export
file format.

e. Automatic file backup feature has been temporarily removed as a bug in the
compiler causes corruption of an area of memory in which the chart data is
stored. Depending on the chart complexity and layout, chart (file) corruption
could occur.

f. Fixed a problem which resulted in inaccurate placement of labels in zoom
modes 2 and 4. This could result in portions of label text characters being
lost when printing at 300dpi resolution on LaserJets.

v1.29  2/8/90

a. Fixed a problem which causing loss of some parts of symbols and lines when p
rinting at 150dpi on LaserJet printers in LANDSCAPE mode.

b. Fixed a minor annoyance which would result in inversion of the image
wherever portions of label text characters were located on top of symbols or
lines.

v1.30  2/12/90

Fixed a problem which would result in a 'String Space Corrupt...' error
message when using certain options after adding a TEXT Block to the chart with
the 'Allow Label Place' option Off.
