4FILES Version History
----------------------
v-3.24 Oct
======
-- Under DesqView/X, the Scroll-Lock key was not recognized. It is now,
but the key must be pressed twice. This is a problem with DVX, not
4FILES. Shift-UpArrow and Shift-DownArrow are non-functional under
DVX, for the same reason.
v-3.30 Dec 6, 1995
======
-- Added new macros for specifying command lines for programs mapped into
utility ports. (See $0 and other numbered macros in 4F.TXT.)
-- Several refinements and bug fixes.
v-3.23 Aug 25, 1995
======
-- Cures video conflicts unique to operation under DesqView and DesqView/X.
The cure results in the Ctrl-F7 feature being disabled under DV and DV/X,
since the setup for it relies on hardware level access to the video
system, which neither will tolerate reliably. DV and DV/X can configure
the number of rows displayed without relying on Ctrl-F7 anyway.
v-3.22 June 21, 1995
======
-- Fixed a bug in version 3.21 that was causing the image in memory of part
of the configuration data to be overwritten during some operations.
-- Changed the sort routine so the ".." directory always appears above
subdirectories starting with unusual characters such as "!" or "%".
This allows the Grey-Minus or (on laptops) the "]" key to move up the
directory tree properly.
v-3.21 June 6, 1995.
======
-- Before calling an external program, existence of the program is tested.
This speeds executions relying on the PATH and makes a more specific error
message possible.
-- When creating an archive, if a target filename is inadvertently omitted the
user is now prompted for one. Otherwise the result could be to create an
archive named, for example TARGPATH.ZIP, rather than intended placement of
an archive in the directory TARGPATH.
-- Beeps are now generated by a different method, to avoid a long, harsh
beep on some laptop computers.
-- At the end of a very long directory listing, Page Down was scrolling back
to top of the directory listing if the next page down was partial screen,
due to a signed rather than absolute comparision. Fixed
-- For new users who do not yet have a TEMP directory set up, directory
creation during file copying now functions.
-- In OS/2 and Windows, <LeftShift><ESC> now quits to the current directory
and <RightShift><ESC> quits to the original.
v-3.20-c: Feb 14, 1995
=========
-- Previously hidden directories were listed, but they were not recognized
as existing directories when trying to copy or move files into them.
Fixed.
v-3.20-b: Jan 6, 1995
=========
-- New macros are now supported in the command tail fields during utility port
configuration. $D inserts the drive:pathspec\filespec. This is in
addition to the existing $P, $F and $N macros.
v-3.20: Dec 17, 1994
=======
-- Improvements to the system for restoring the original video mode at exit
and when calling other programs, including restoration of the original font.
-- Improvements to handling of DOS critical errors (for when trying to read
an unformated disk, etc.), for smoother operation of 4FILES and better
messages for the user.
-- When copying files (etc.), when tabbing back to the target path field after
entering a new name in the name field, only 12 characters would be accepted
in the path field. Fixed.
v-3.19: Oct 12, 1994
=======
-- With LCD or any other change-directory utility active, and when copying
from a write protected disk, if a directory had to be created on the
target disk a "write protected" error was shown on the bottom line,
even if the target disk was not write protected. Directory creation
was not attempted, and a file was created instead. Fixed.
-- Several minor refinements to operations.
v-3.18: Sept 12, 1994
=======
-- Further improvements for network operation.
-- Corrected recent problem, inability to create a new directory
while copying files (in cases where 4FILES is not configured to use
directory utilities such a LCD).
-- Documentation updated.
-- Documentation corrected, re: how to use executable extensions.
-- NEW PRODUCT ANNOUNCEMENT: 4FILES-PRO, described on this disk in
4F.TXT, page 2. Upgrading to this enhanced, non-shareware version is
inexpensive for registered users of 4FILES.
V-3.17b: June 22, 1994
========
-- Under Novell NetWare a ".." entry was not produced in the directory
listing, defeating the function of the Grey-Minus key. The ".." record
is now added if not found in non-root directories.
-- The label for the parent directory, rather than "<-DIR->" replaces the
characters with upward arrows (not reproduced here to avoid printer
conflicts if you print this file.
-- If a floppy is swapped but the descript.ion file is yet to be written,
it was possible to get into an endless loop of "replace disk" prompts.
You can now break out from a prompt if this happens.
V-3.17: June 17, 1994
=======
-- If 4F is configured to use LCD for changing directories and a CD operation
fails, you will now be prompted to have LCD rescan the directory tree.
The LCD utility port has a "/SCAN" entry. You may make this "/SCAN DC"
if you want to scan only hard drives D and C. Unfortunately, this rescan
function is not available for ACD; ACD displays a directory tree to choose
a directory from rather than reporting an error in ERRORLEVEL.
-- As soon as a CD operation starts, the 4F listing and count of files and
bytes are now cleared -- only the current directory shows on in the 4FILES
screen framework until the new directory has been loaded. For large
directories or slow networks, this makes it clear that something is
happening during the CD.
-- On upward CD's from a subdirectory named AAA.002, if there is a
subdirectory in the parent named AAA.001, .001 rather than .002 became
the current record in the parent. Fixed.
-- Copying to ".." was not working. Also, for copying to an existing directory
named ..\..\AAA, the directory was not being found to exist. Both fixed.
-- Detection of write protected disks was disabled due to a conflict with a
genuine bug in DOS, encountered with a change in v-3.15. 4F now works
around the bug.
-- The (K)ill directory command no longer rereads the directory when finished.
V-3.15:
=======
-- Configuration switch added to determine whether or not you will be prompted
for each file when copying or moving marked files (has no effect if running
under COMMAND.COM).
-- Failure to create new directory during copy using the ".." directory name
has been corrected.
-- Switching or restoring (after calling a utility) the number of screen rows
has been improved.
-- Fixed problem with branded-as-registered copies losing their brands (on an
infrequent basis).
V-3.13 Fixes:
=============
-- If the video mode was changed in a utility called from within 4FILES,
upon returning to 4FILES garbage was displayed after the video mode was
restored. Fixed.
-- The Shft-DEL and Shft-INS keys are once again functional.
V-3.12 Fixes:
=============
-- Restoration of the original DOS screen failed if the TEMP directory
was a subdirectory rather than a root directory. Fixed.
-- An error in at least one type of AMI BIOS chip caused keystrokes for
yes/no prompts to be lost before being acted on, putting the computer in an
endless loop. One function on this BIOS trashes a register that should be
unaffected; 4FILES now restores the register after the BIOS call.
-- Instructions for Windows installation in 4F.TXT improved.
V-3.11 Improvements
===================
VIDEO:
======
-- Video mode selection with Ctrl-F7 has been improved. This includes
detection of ANSI if it is active, enabling use of compatibl
