Check through this file for a comprehensive list of what's changed since
version 2.51. Additional documentation on new features is in the online
help. Information about product changes before version 2.51 may be
viewed at our web page (http://www.jpsoft.com) by selecting 4OS2 and
then Product History.
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 4OS2 with version 2.52, you can skip this file entirely, and
begin with the 4OS2 Introduction and Installation Guide.
This file is divided into the following sections:
General Features and Enhancements
Startup and Initialization
Variables and Variable Functions
Command Changes
Technical, Compatibility, and Bug Fixes
Major 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 4OS2 LIST
command, or printed on most PC printers using the command:
copy updat252.doc prn
Printing it with a program that formats the pages is not likely to work
due to the formatting included in the file.

4OS2 2.52 Change List
General Features and Enhancements
---------------------------------
==> Increased the maximum history size from 8K to 32K.
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.
==> SwapFilePath: Can now specify a path or a filename (previously
you had to specify the whole file name). If you leave off the
name, 4OS2 uses the path you specify with the default name
SWAPPER.DAT.
Internal Variables and Variable Functions
-----------------------------------------
==> @EXT: Increased the maximum length returned to 64 characters.
Command Changes
---------------
==> ** SHRALIAS: Rewritten as a mixed internal/external command, rather
than just an external program. You must now run the internal
command, not the external program, and make sure that
SHRALIAS.EXE is in the 4OS2 directory or in your path. To
convert from the previous version of SHRALIAS, remove the
extension and path from any SHRALIAS reference, so that the
internal command is used (you can no longer run the external
SHRALIAS.EXE directly). The internal SHRALIAS /U command may be
used to unload SHRALIAS.EXE.
==> FOR: Enabled extended parent directory names.
Technical, Compatibility, and Bug Fixes
---------------------------------------
==> 4OS2 now accepts the '/' as a valid filename character in the
target filename for input or output redirection.
4OS2 2.52 [04-17-96] UPDAT252.DOC page 2
==> Added a check for escaped characters in a redirected filename.
==> 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 files executed via executable extensions.
Double quotes are now added if the name contains whitespace.
==> Fixed a problem with multiple pipes where the first command being
piped to was an external console-mode application (e.g. DIR |
SORT | TEE FILE.DAT).
==> Fixed a minor problem with pipes of the form "prog1 | *prog2".
==> Fixed a rare problem when piping from an internal command that
didn't support command grouping, to an internal or external
command that ended with a '('.
==> Fixed a problem with NUL characters in batch files.
==> 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.
==> IF: Added a work-around for constructs like:
if 1 == 0 echo foo && echo bar
to emulate CMD.EXE's (undocumented) behavior of basing the &&
condition on the result of the IF test.
==> 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.
