- Check through this file for a comprehensive list of what's changed since
- version 5.51. Additional documentation on new features is in the online
- help. Information about product changes before version 5.51 may be
- viewed at our web page (http://www.jpsoft.com) by selecting 4DOS and
- then Product History. Many product history files are also available in
- our Compuserve forum (GO PCVENB or GO JPSOFT, library 10 / JP Software,
- look for files named UPxxxxxx.ZIP).
-
- Some of the descriptions below may be more detailed than you need; if
- you aren't using a feature, feel free to skip to the next item. If you
- are new to 4DOS with version 5.52, you can skip this file entirely, and
- begin with the 4DOS Introduction and Installation Guide.
-
- This file is divided into the following sections:
-
- General Features and Enhancements
- Startup and Initialization
- Command Line Editing Changes
- Command Changes
- Technical, Compatibility, and Bug Fixes (General)
- Technical, Compatibility, and Bug Fixes (Windows 95)
-
- Significant new features and those which affect most users are marked
- with "**" in the lists below. Other items discuss smaller or more
- technical changes.
-
- This file is formatted at 58 lines per page, and contains form feeds and
- page footers. It can be viewed with a file viewer such as the 4DOS LIST
- command, or printed on most PC printers using the command:
-
- copy updat552.doc prn
-
- Printing it with a program that formats the pages is not likely to work
- due to the formatting included in the file.

- 4DOS 5.52 Change List
-
- General Features and Enhancements
- ---------------------------------
-
- ==> ** In Win95, file searches now look for long filenames and then
- short filenames. For example, suppose you have two files on your
- system:
-
- Long Name Short Name
- ------------------ ------------------
- My Letter.DAT MYLETT~1.DAT
- Files.DAT MYFILES.DAT
-
- A search for MY*.DAT will now find both files; previously it
- would find only the first file. This was done to improve
- compatibility with COMMAND.COM and to make the results more
- intuitive.
-
- CAUTION: Extra care should be taken performing certain commands
- on long filenames (e.g. using wildcards to delete or move files),
- as they may now affect files with short names as well. For
- example, DEL *1 will delete all files whose names end in "1".
- Because short filenames generated by Windows 95 end in "~1", such
- a command would delete all of those files -- probably not the
- result you wanted.
-
-
- Startup and Initialization
- --------------------------
-
- ==> Added a new .INI directive:
-
- AppendToDir = [Yes | NO]: If set to "Yes", TCMD will append
- a trailing \ to directory names when doing filename
- completion.
-
-
- Command Line Editing Changes
- ----------------------------
-
- ==> ** In Win95 a Ctrl-A on the command line during filename expansion
- will now toggle the returned filename between long filename (LFN)
- and the traditional short name (SFN) format. The default is LFN
- format; if you switch to SFN format the change will only remain
- in effect for the current filename expansion. Any new expansion
- sequence later on the command line will start in LFN format, and
- can be toggled to SFN format with another Ctrl-A.

-
-
- Command Changes
- ---------------
-
- ==> FOR: Enabled extended parent directory names.
-
-
- Technical, Compatibility, and Bug Fixes (General)
- -------------------------------------------------
-
- ==> DESCRIPT.ION now allows either a space, tab, or comma as the
- delimiter between the filename and the description (for
- compatibility with some third-party description files).
-
- ==> Fixed a problem with NUL characters in batch files.
-
- ==> Fixed a minor problem with pipes of the form "prog1 | *prog2".
-
- ==> Fixed a problem with files executed via executable extensions.
- Double quotes are now added if the name contains whitespace.
-
- ==> Fixed a sporadic problem with a ^C in DO if the DO test performed
- disk or keyboard I/O.
-
- ==> Fixed a problem with redirection and NoClobber (NoClobber was
- effectively being ignored).
-
- ==> The PATH search routine now queries if the specified drive is
- ready before attempting to find the external command, to avoid a
- critical error message.
-
- ==> DO: Now allows embedded equal signs in a test condition.
-
- ==> FOR: Fixed a problem with include lists in the FOR arguments.
-
- ==> INPUT: Fixed a problem with using INPUT /E in a transient shell
- and solved a problem with INPUT /W /E which prevented the
- existing value from being displayed unless you pressed a key.
-
- ==> LIST: Fixed a sporadic problem with Find with wrapping on. Also
- improved LIST's ability to find the end of each line properly in
- files with unusual line terminations (e.g. CR or LF alone, LF/CR,
- CR/CR/LF, etc.).
-
- ==> MD: Fixed a problem with /S and UNC names.
-
-
- Technical, Compatibility, and Bug Fixes (Windows 95)
- ----------------------------------------------------
-
- ==> 4DOS now now strips quotes from the PATH string where required
- under Win95. This is necessary for compatability with
- COMMAND.COM.
-
-
-
- 4DOS 5.52 [04-17-96] UPDAT552.DOC page 3
-
-
- ==> Added support for the Win95 behavior of looking for WINBOOT.INI
- first for options like "BootGUI", then looking in MSDOS.SYS if
- WINBOOT.INI isn't found.
-
- ==> Changed Win95 detection method. This should avoid any cases
- where 4DOS confused Win95 with PC-DOS 7.0.
-
- ==> Fixed a problem with AutoExecParms under a Command Prompt Only
- boot.
-
- ==> Fixed a problem which was leaving the MSDOS.SYS file open after
- booting Win95 with BootGUI=1.
-
- ==> Improved network support for long filenames in directory and
- filename completion.
-
- ==> Worked around a Win95 bug with descriptions on an LFN drive (4DOS
- would occasionally display the wrong descriptions for some
- files).
-
- ==> DESCRIBE: Fixed a problem with placing the description on the
- command line (4DOS couldn't always tell if a quoted string was a
- description or a file name). Also fixed a problem with wildcard
- DESCRIBEs under Win95 when the description was NOT included on
- the command line.
-
- ==> LOCK / UNLOCK: Enabled these commands in MS-DOS 7 (without the
- Win95 GUI loaded).
