can ONLY be used for PKZIP 2.0. Removed support for old PKZIP
1.1 -ei parameter. (ZIP2) ZIP1 and ZIP4 are compatible with
both PKZIP 1.1 and 2.0. See ZIPR.DOC for more information.

12-26-92 ■ Version 1.5

line.

available.
. Added safety check to log to proper directory after program
execution.
. Added safety check to log to proper directory prior to program
execution.
. Added code to perform operations prior/subsequent to program
execution. ZipFile.IN commands are passed to COMMAND.COM
prior to program. ZipFile.OUT commands are passed to
COMMAND.COM subsequent to program.
. Added check to prevent compressing the \ZIPR sub-directory.
. Removed unnecessary variable declarations.
. Added TokenName variable to reduce code size and complexity.
. Removed internal dependence on %1 and %2 variables.
. Moved CheckCommandLineLength subroutine to ERROR??.OBJ.
. Split main program and message screens into separate modules.
(<64K .OBJ)
. Removed internal dependence on %3 and %5 variables.
. Solved cursor problems using a combination of methods.
Re-enabled cursor after prelog, epilog, help, and error
screens. Eliminated cursor prior to prelog, epilog, help, and
error screens. Positioned cursor at the bottom of the screen
during ZIP'R messages.
. Re-enabled cursor during prelog, epilog, help, and error
screens. Stowaway would not display the cursor when run
through ZIP'R. Rolodex Live! would not display the cursor
when run through ZIP'R.
. Corrected ZIPRTAME.BAT statement. (Extra spaces in "SET
ZIPR=C:\ZIPR")
12-16-92 ■ Version 1.4ß
. If you are updating ZIP'R from a version older than
1.2ß, rename the file ZIPR.COM to ZIPR.OLD, and the file
ZIPRN.COM to ZIPRN.OLD. Copy the new files into the
\ZIPR sub-directory. You may have to update menu
programs, Windows, and DESQview to reflect the new .EXE
extensions for ZIPR.EXE and ZIPRN.EXE.
. Added subroutine to center command line display.
. Added command line display to prelog screen.
. Added ZIPRTAME.BAT file to allow TAME to be loaded before
ZIP'R. See the ZIPR.DOC file for additional information.
. Removed trailing spaces at the end of some statements.
. Replaced %ZIPR% environment variable with internal ZIPRPath
variable.
. Eliminated cursor during prelog, epilog, help and error
screens.
. Added User# variable to reduce dependency on DOS environment.
. Added DelayTime variable to adjust the registered/non-
registered delays.
. Added ZIPRVersion variable to easily update version numbers.
. Added encryption to variables and command lines.
. Fixed problems with various ZIP'R messages not clearing the
screen.
. Converted many existing lines of code into various
subroutines.
. Updated and enhanced prelog, epilog, help, and error message
screens.
. Removed automatic TAME loading to allow proper swapping under
DV/WIN3. If TAME-RES is loaded, DOS can't reclaim the memory
after ZIP'R swaps. This change increases available memory
under DV/WIN3 by about 45K.
. Fixed missing quotes in ErrorCode variables.
. Fixed problem with compression/decompression token file
detection. Token files were only being looked at if a valid
compressed file existed.
. Incorporated all help/error/prelog/epilog screens into ZIP'R.
Created subroutines for Prelog, Epilog, Help, and Error
Messages. ERRORN.COM file is no longer needed. ZIP'R version
1.4ß no longer requires the ERRORN.COM file. Rename this
file ERRORN.OLD.
. Corrected help screen (ZIPR.EXE vs ZIPR.COM).
12-11-92 ■ Version 1.3ß
. Added missing "IF EXIST" statements to DecompressZipFile
subroutine.
. Changed "Done" section to use BLDChDrive and BLDChDir instead
of "Run".
. Optimized "Quit" section using "Contains" to reduce code size.
. Replaced "Run ERASE ..." statements with "BLDDel" to increase
speed.
. Now using "RunString" on decompression commands to return
ERRORLEVEL.
. Added ZipName, ZipType, ProgramName, PP1, PP2, PP3, and PP4
variables.
. Removed extraneous ^^ symbols from strings.
. Added DecompressZipFile subroutine.
. Added CompressUsingARJ subroutine.
. Added CompressUsingLHA subroutine.
. Added CompressUsingZIP subroutine.

. Now loading secondary command processor to improve
reliability.
. Changed delay timer to new format (WAIT).

needed.
. Added CheckForAvailableUsers Subroutine.
. Added LogToDriveAndDirectory Subroutine.
. Added CheckIfTameNeeded Subroutine.
. Command line parameters now converted to UPPERCASE.

deleted.
. Changed to totally new compiler. (Many nagging bugs fixed!)
11-28-92 ■ Version 1.1ß
. Removed %5 vs %5 %6 %7 %8 %9 statements. (New compiler fixes
