ZIP'R For DOS (Network/Multitasker) Revision History 09-14-93 ■ Version 4.12 . Added support to read the two new parameters from the [VIDEO] section of the .ZIF file. . Added code to allow the output of the compression programs to be suppressed when compressing or decompressing a file. (The output cannot be suppressed during temporary file creation, due to a conflict with the method used in this routine.) . Added code to allow the selection of screen write modes. Choices are BIOS, Direct, or AUTO. 08-14-93 ■ Version 4.11 . Added date code to indicate the date of the last internal code change. . Wrote common routine to display the Prelog, Epilog, and Update nag screen backgrounds. (Reduced program size by about 6K.) 07-05-93 ■ Version 4.1 . Corrected problems in the RegistrationNumber processing routine. . Removed references to RegistrationCity in all routines. . Streamlined code in EXEC module to reduce code size. . Modified ZIPR.INI read routine to read new style Registration section. (Dropped support for old style.) . Combined separate ZIPR.INI read routines into one sub-routine. . Re-wrote entire ZIPR.INI read routines to prevent possible problems when reading the ZIPR.INI file. . Added commands to swap ZIP'R to disk and load the specified command processor when executing a .IN or .OUT command. . Removed implicit references to COMMAND.COM (SYSTEM) in the .IN and .OUT file processing routines. . Corrected a potential problem where a hard-coded "COMMAND /C " was being issued to automatically execute the ZIF Editor if no command-line parameters were passed to ZIP'R. 06-12-93 ■ Version 4.0 . Released ZIP'R v4.0 with version 2.0 of the ZIF Editor. 06-11-93 ■ Version 3.3 (Internal BETA Version. Not Released.) . Eliminated slow screen drawing commands in the prelog screen routines. (The speed increase will be most noticeable when running under Windows.) . Revised prelog screen. New screen eliminates unnecessary information and presents the remaining information in a more visually appealing form. . Added installation program to automate the installation process. ZIP'R will now be distributed with the INSTALL.EXE and ZIPR??.BCF files only. . Updated registration number code. . Changed the location of the DontInterruptCompMessage subroutine to eliminate the red flash prior to displaying the query dialog box. . Removed hard-coded "C:" drive specification when ZIP'R exits. Previously, ZIP'R would log to the root directory of the C: drive. Now, ZIP'R will log to the root directory of the drive on which ZIP'R was invoked. . Removed hard-coded "COMMAND.COM" references, and replaced them with information gathered from the COMSPEC variable. This should allow COMMAND.COM replacements, such as NDOS.COM and 4DOS.COM to operate correctly. . Removed dependence on the "System REM >" call to create zero-length token files. Now open a file and write the filename to it. (This method is faster, and will not cause problems for NDOS, and possibly 4DOS.) . Created TK1FileName and TK2FileName variables to contain the full path to the token files. . Modified command-line parameter handling to automat- ically load the ZIF Editor if no parameters are entered on the ZIP'R command line. . Enhanced the AlternateDIR feature of ZIP'R to allow moving more than one level deep from the compressed file. This enhancement allows ZIP'R to be completely compatible with the Alternate Compressed File Directory feature of the new ZIF Editor. . Corrected a potential problem when reading .ZIF files. A GoTo label was placed in an IF...Then loop, which could have caused problems. . Corrected a problem reading the "CompressedFileName=" entry in the new style .ZIF files. (New style .ZIF files contain the compressed file extension, and this must be removed before passing to ZIP'R.) . Added code to read new style .ZIF files generated by version 1.4 of the ZIF Editor. . Corrected a display problem where a long command line would corrupt the error message screen. . Added new FieldLength variable and deleted other field- specific length variables in the prelog subroutine. . Modified prelog screen to allow room for information regarding Cluster Size, Accurate File Size Calculation, and Sorted Extraction. . Improved the speed of the deleted file scanning routine by deleting all files and/or sub-directories at once, rather than one at a time. 05-02-93 ■ Version 3.2 . Fixed problem with ZIP'R not deleting .TK4 and .TK5 files when using the "Update" option. . Added a check in case one of the .TK4 or .TK5 files does not exist, to make sure that both files are deleted before returning from the subroutine. . Changed "Update Only" to "Update" on the Update nag screen. . Added a check to make sure that the .TK4 and .TK5 files exist before scanning for deleted files. This prevents ZIP'R from displaying the "Scanning for deleted files..." message when compressing a program that was left in an uncompressed state. (This can occur when using the "ZIP-Q-U" options, and choosing not to compress the program after exiting the first time.) . Added a check to make sure that the .ZIP file exists before generating the .TK4 and .TK5 files. This prevents PKUNZIP.EXE from generating an error message. . Added a jump to display the "Scanning for deleted files..." message if more than one file/directory was deleted from the .ZIP file. This prevents the message from scrolling off the screen. . Changed "Searching for deleted files..." message to "Scanning for deleted files...". . Changed message during the check for deleted files from "Compression in progress..." to "Searching for deleted files...". . Added a 32-bit CRC check comparing the old and new file lists. If the two values match, do not check individual files for deleted files/directories. . Added twirling bars to the "Compression in progress. Do NOT interrupt!" screen. This feature provides an activity indicator during processing. . Fixed a bug in the "Update" routine that was causing ZIP'R to fail to delete a user-deleted file from the original .ZIP file. . Fixed a bug in "Update" routine that was deleting the wrong files from the original .ZIP file. (No data was lost, because PKZIP updated the missing files.) . Added error message if "-U" option is used with ARJ, LHA, or SQZ. (These programs do not yet perform the necessary list file creation.) . Added "Query" code to ARJ, LHA, and SQZ modules. . Fixed a problem with multiple accesses to a program when the "Update" option was being used. Since the .ZIP file is not deleted in this situation, the second (or subsequent) copy of ZIP'R would try to decompress the file. Added a check for a .U?? file to prevent this from happening. . Added delay screen with pause when unregistered copies of ZIP'R use the "Update" feature. . Fixed problem with ZIP'R not deleting the original .ZIP file if the "Update" option was also selected. . Added "Query" feature to ZIP'R For DOS. Adding "-Q" to the type of compression field will prompt the user whether to re-compress the program after it is exited. . Reduced code size in ZIP and ARJ modules by combining redundant character strings into variables. . Added code to clear the screen between .TK4 and .TK5 creation routines. . Changed the name of ZIP'R to ZIP'R For DOS. . Combined .TK4 and .TK5 creation routines into a single sub-routine. (OldFileList and NewFileList) . Shortened PKZIP command lines to reduce code size. . Fixed a display problem when the "Update" code deleted a file from an existing .ZIP file. . Fixed a bug when reading the temporary file list files that would never find a deleted file. (EOF marker was always found immediately.) . Changed method of comparing old and new file lists from String Arrays to standard files. Compiler problems caused String Arrays to be too unreliable. This method is slower, but does not have a limit on the number of files that can be handled. . Added code to suppress the deletion of the .ZIP file after decompression if "-U" appears in the ZipType entry on the command line. . Added support to read the "-U" (Update Only) option from the command line. . Preliminary testing on the "Update" code indicates up to a ten-fold improvement in compression speed. The most improvement is achieved on directories containing a small number of large files. Improvements of about 25% are achieved on directories containing a large number of small files. (Code optimization should be able to improve this even further.) . Corrected a problem in the "Update" code where data from the old and new file lists was not being transferred to the arrays properly. (This caused an erroneous mis-match between the two array lists.) . Fixed a bug in the "Update" code where reading a line that contained an EOF marker as the last character would prematurely abort. (The solution is to read the line before checking for the EOF marker.) . Preliminary coding begun for "Update" compression. . Updated internal registration information. . Improved the accuracy of the Conventional memory calculation on the prelog screen. (This figure should still be slightly low, depending on the size of COMMAND.COM and environment. 03-24-93 ■ Version 3.1 . Added time stamp on all files to indicate the version number. . Added code to create another random filename if the file corresponding to the first filename created already exists. This could happen if a directory became filled with undeleted signal files, or if another copy of ZIP'R had created a file with the same name (very unlikely). . Changed ARJ compression and decompression command lines to place all the options in the same area. . Removed extra registration slots to reduce code size by about 20K. . Added code to allow retail shareware versions to be registered. . Now use BIOS when displaying "Calculating disk space required for decompression..." warning message to prevent SQZ from overwriting previous text. . Changed the method used to read the temporary file, which increased the speed of the Accurate File Size Calculation by almost a factor of two! 03-14-93 ■ Version 3.01 . Registration updates to ZIP'R. ZIF Editor v1.1 included in this release. 03-09-93 ■ Version 3.0 . Released to public as version 3.0. 03-09-93 ■ Version 2.6 . Fixed problem with ZIP'R finding compression programs located in the \ZIPR sub-directory if no path was specified in the ZIPR.INI. . Added initial "NO" value to SortedExtraction variable. 03-08-93 ■ Version 2.5 . Added .ZIF file example to ZIP'R help screens. . Removed unnecessary variable declarations from ZIPR??.OBJ. . Fixed problem where DOS would report a "Path not found." error message if there was no path. . Fixed potential problem with closing files that may not have been opened. . Fixed problem with shifting and unshifting non- existent DOS variables. (Compiler corruption problem.) . Compressed executable files to minimize disk space used by ZIP'R. ZIP'R executables now consume about 140K, instead of 790K! In addition, the program loads more quickly on my test system. Your mileage may vary. . Streamlined code in ZIPRN module to reduce program size by about 1K. (Moved percent variables to common section.) . Added support to read Program Concurrent Access information from .ZIF file. This information is no longer supported in the ZIPR.INI file. 03-05-93 ■ Version 2.4 . Unreleased internal version, in preparation for ZIP'R v3.0. . Streamlined code in EXEC module to reduce program size by about 1K. . Streamlined code in INI and REGA modules to reduce program size. Code size reduced by about 2K. . Modified conventional memory calculation to calculate available memory after ZIP'R swaps to EMS or disk. . Added support to ZIP'R to read alternate program directory information from a .ZIF file. . Worked around a problem where "Compression in progress..." and "Decompression in progress..." error messages were being overwritten by ARJ and SQZ. (Problem related to Use Direct command.) . Added temporary registration numbers to ZIP'R code to allow phone registrations. . Removed ZIP'R feature matrix variables from ZIP'R, since they are not presently being used. . Added check for a non-existent .ZIF file. Display error message if file can not be found. . Added "ParameterCount" variable to indicate the number of command line parameters. This variable is modified directly when a .ZIF "Parameters" string is used. . Added support to read "Parameters" string generated by the ZIF Editor. . Added command line processing to detect whether .ZIF file information should be used instead of the command line parameters. . Modified ProcessCommandLine sub-routine to reduce dependence on DOS % variables. . Moved common routines from ZIPR??.OBJ and ZIPRN??.OBJ to EXEC??.OBJ. 02-22-93 ■ Version 2.3 . Removed extraneous variable declarations from ARJ, LHA, SQZ, ZIP, ERROR, EXEC, and INI modules. . Added passed parameters P4 - P8 to help screens. . Added support to handle the display of extremely long ZIP'R command lines on the prelog screen. Lines longer than 75 characters are truncated, and a warning message is displayed. The actual command line is not affected by this truncation, only the display on the prelog screen. . Moved part of the code in the EXEC??.OBJ module to the newly created INI??.OBJ module. . Added the capability to pass up to eight parameters to a program being executed through ZIP'R. Previous versions were limited to four. . DESQview users must check the setting of: Writes text directly to screen.......: [Y] Since ZIP'R now uses direct screen writes to perform some of its screen operations, this must be set to "Y". . Added code to work around a problem with using direct screen writes in combination with box drawing routines. Boxes would be drawn incorrectly if BIOS mode was not used for these routines. . Enabled direct video writes if a VGA adaptor is detected. This increases the screen display speed under Windows and DESQview. . Added check for /h, /H, or /? as the first parameter on the command line, and if so, display the help screen. Example: ZIPRN /H . Changed help screen text color to Bright White to allow screen captures to work properly. . Added check to see if ARJ.EXE, LHA.EXE, SQZ.EXE, PKZIP.EXE, or PKUNZIP.EXE are available when needed. ZIP'R will now issue an error message if the proper file can not be found in the ZIP'R sub-directory or in the directory specified in the ZIPR.INI file (registered versions only). . Corrected NoZipType error message display when %3 is not specified on the command line. . Added path options for compression programs. Registered users may now specify a path for each compression program used by ZIP'R. These paths are specified under the [OPTIONS] section of the ZIPR.INI file. Each path must be on a separate line, and must be followed by a backslash. Example: ARJ=C:\COMPRESS\ARJ\ LHA=C:\COMPRESS\LHA\ SQZ=C:\COMPRESS\SQZ\ ZIP=C:\COMPRESS\ZIP\ 02-14-93 ■ Version 2.2 . Moved CompressionInProgress, DecompressionInProgress, DontInterruptCompMessage, and DontInterruptDecompMessage subroutines to ERROR??.OBJ file. . Modified command line display area on the prelog and error message screens to only show "ZIPR" or "ZIPRN" instead of the fully qualified path. . Added SQZ to error messages and help screens. . Added check for invalid compression type. . Added command line display to all error message screens. . Corrected NoCommandProcessorOnPath error message, which was referencing CONFIG.SYS instead of AUTOEXEC.BAT. 02-07-93 ■ Version 2.1 . Added SortedExtraction= option to ZIPR.INI file to allow files to be extracted in alphabetical order. Registered users may add the line SortedExtraction=YES to the [OPTIONS] section of the ZIPR.INI file. This feature will have the effect of sorting all extracted files by name during the extraction process. This feature works with PKZIP/PKUNZIP v1.1, 2.04c, and 2.04e. It does not work with ARJ, LHA, or SQZ at this time. If future versions of these archivers support this option, ZIP'R will be updated accordingly. . Improved AccurateFileSizeCalculation routine to compensate for wasted space due to cluster size (allocation units) when files are decompressed. The default cluster size used for these calculations is 4096 bytes. Registered users may add the statement ClusterSize= to the [OPTIONS] section of the ZIPR.INI file. The default value is ClusterSize=4096. Valid cluster sizes are 512, 1024, 2048, 4096, and 8192. . Changed PKUNZIP command line to use the "brief" method when calculating the disk space required for successful decompression. This increases the speed of this calculation slightly. . Changed "Calculating required disk space. Please wait!" error message to read, "Calculating disk space required for decompression. Please wait!" . Added the ability to execute programs that are located one sub-directory below the compressed file. To utilize this feature, specify the sub-directory (enclosed in backslashes) immediately prior to the executable file name on the ZIP'R command line. Example: ZIPRN C: \TEST TEST ZIP \SUBTEST\PCSHELL . Added the ability to detect VCPI memory if running under MS-DOS 5 with EMM386.EXE loaded. . Moved prelog and epilog display routines to separate PRE??.OBJ module. 01-31-93 ■ Version 2.0 . Fixed a bug that would cause ZIP'R to hang if no EMS memory manager was present. (Now detects if QEMM, 386MAX, or EMM386 is present before checking for EMS memory.) . Fixed a bug that would cause ZIP'R to hang if no VCPI provider was present. (Now detects if QEMM or 386MAX is present before checking for VCPI memory.) . Added support for registered users to defeat the accurate file size calculation if disk space is not a problem. The following line should be added under the [OPTIONS] section of the ZIPR.INI file: AccurateFileSizeCalculation=NO . Added [OPTIONS] section to the ZIPR.INI file. . Changed ARJ and LHA command lines to use the shorter "List" command instead of "View". (Speeds up the file size calculation.) . Corrected a problem in the CalculateExactFileSize subroutine, where a string variable was being used in an "Open" command, causing a myriad of problems. . Changed logic for more accurate detection of .ARJ, .LZH, .SQZ, and .ZIP file information. . Added code to calculate the exact amount of disk space needed to decompress .ARJ, .LZH, and .SQZ files. . Moved CheckSpaceForDecompression subroutine to EXEC.OBJ. . Corrected HelpCode error in ZIPRN.EXE that would call the wrong help screen. (ZIPRHelp vs. ZIPRNHelp) . Added /x$QZ$$ZQ$.LST switch to SQZ command line to prevent error message when attempting to move that file. . Added CLS to clear the screen before displaying the warning message screens. . Added warning message to wait for disk space calculation. . Added code to calculate the exact amount of disk space needed to decompress a .ZIP file. . Added code to generate psuedo-random filename for temporary token file. (.TK3) . Added preliminary support for SQZ. (Version 1.08.03 or higher required for "Move" operation. Does not support errorlevels, so use is risky at this time.) 01-28-93 ■ Version 1.9 . Added 386MAX installed and version number information to prelog screen. . Added VCPI installed and version number information to prelog screen. . Enhanced prelog screen with additional information. (QEMM installed and version, DPMI installed and version, EMS version, and XMS version.) . Added check to see if XMS memory is installed prior to evaluating the amount of memory installed. (Compiler documentation recommends this.) . Now swapping ZIP'R to EMS/Disk to provide additional room for compression programs. (No known problems have been encountered, but this step was taken as a precaution.) . Now swapping ZIP'R to EMS/Disk to provide additional room for decompression programs. (Fixes problem where compressed file could get deleted when running under DESQview with very small windows. DOS would issue an out of memory error, but no errorlevel would be set because the decompression program would not run.) . Added textured background to error message screens. 01-23-93 ■ Version 1.8 . Changed format of ZIPRN.REV file. . Updated ZIPR.DOC file with ZIPR.INI related information. . Convert PrelogDelay= and EpilogDelay= statements in ZIPR.INI to upper case. . Moved PrelogDelay and EpilogDelay to separate [DELAYS] section in ZIPR.INI. [DELAYS] section contains PrelogDelay=?? and EpilogDelay=?? delays. . Shortened variable names in ERROR?? module. . Added "Delaying... ??" message to epilog screen. . Added registration information to epilog screen. . Added "Delaying... ??" message to prelog screen. . Shortened ProcessZIPRINI... variables. . Isolated problem with opening a non-existent .IN or .OUT file. (LPT1: Not printing.) . Added EpilogDelay and PrelogDelay options to ZIPR.INI file. (Registered version only.) . Updated prelog to contain additional information about EMS, Environment, XMS, DESQview, Windows, and a "Future" section. . Added compression and decompression in progress warning messages. . Moved individual ARJ, LHA, and ZIP compression routines to separate .OBJs. . Added encryption to COMP??.OBJ file. . Added [REGISTRATION] section, containing registration name and number, to ZIPR.INI file. . Eliminated unnecessary strings and declarations in various modules. . Reduced code size by using new centering routines. . Shortened background display routines for all screens. . Tightened up .TK1 and .TK2 creation/detection routines. (Network problem.) . Assigned initial PadCharacter value for .U?? and .C?? processing. . Convert ZIPR.INI [-------] statements to uppercase before processing. . Now closing .IN, .OUT, and .INI files after reading. (Network problem.) . Added support for program concurrent access limits to be read from ZIPR.INI. [PROGRAM_CONCURRENT_ACCESS] section contains program names and limits. . Added support to read ZIPR.INI file. . Added copyright notice to prelog screen and documentation. . Added ZIPREnvironment internal variable. . Combined COMP.OBJ and COMPN.OBJ routines into single COMP??.OBJ file. 01-09-93 ■ Version 1.7 . DESQview and Windows users may now need to allocate more EMS memory to programs that are run through ZIP'R. See the DESQview Tips & Techniques section of ZIPR.DOC. . Increased non-registered delays to 10 seconds for prelog and epilog. . Changed order of ZIP options to go from least to most compression. . Located and worked around "tilde problem" in compiler. . Moved compression subroutines into a separate COMPN??.OBJ file. . Added support for PKZIP 2.04c command line troubleshooting parameters. Extended PKZIP parameters can be used by selecting codes from a chart shown in the ZIPR.DOC file. . Some advanced ZIP options have changed: ZIP0, ZIP2, and ZIP3 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. . Added support for new PKZIP 2.04c command line compression parameters. Be cautious when upgrading, as this version of PKZIP has some documented problems. Read the trouble-shooting section of the PKZIP documentation for more information. . Added trailing backslash to internal ZIPRPath variable. . Added registered version support for up to 100 users per compressed file. . Added configurable maximum users allowable. (Default = 2) . Updated help screen display and information. . Clear screen prior to compression and after decompression. . Display COMSPEC path to command processor on prelog screen. . Display error message if COMMAND.COM is not on the path. (DR DOS Problem.) . Revamped error message display routines and screens. . Changed the order that ZIP'R looks for executables to match DOS. (.COM, .EXE, .BAT) . Display help screen after all error messages. 01-03-93 ■ Version 1.6 . Added code to center registered and non-registered text. . Improved insufficient disk space logic when compressed file doesn't exist. . Adjusted insufficient disk space check up to 2.5. (60% compression) . Added check for insufficient disk space before decompression begins. . Added check for a non-existent program name. . Moved common code from ZIPR.OBJ and ZIPRN.OBJ to EXEC.OBJ. . Disabled Prelog screen if PrelogDelayTime is 0. . Disabled Epilog screen if EpilogDelayTime is 0. . Corrected minor centering problem on prelog screen. . Added separate delay times for Prelog and Epilog Screens. . Added Environment Space Available and EMS Memory Available display. . Encrypted text messages in ERROR.OBJ. 12-26-92 ■ Version 1.5 . First non-beta release! All known bugs have been squashed. . Corrected minor centering problem when displaying command line. . ZIP'R now checks to see if the proper decompression program is 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. .
