THD ProScan History ------------------- Aug 20, 1992 - Ver 1.00 - First official release - a command.com compatible counterpart to the THDscan series of upload testers. Sept 28, 1992 - Ver 2.00 - Bugfix - Insert current directory for some "found" utilities during install. Bugfix - Fixed error when extensions not supplied during installation. Bugfix - Added conditional delay to the program, to allow the ansi screen to complete on fast systems. Bugfix - Stopped upper imbedded indicator from flashing during the entire embedded archive testing process. Bugfix - Fixed some errors in the "move" routines which could cause runtime errors. Bugfix - Redirected Scan.exe's output as it seems to find gateway if it is installed. Bugfix - The tester now requires a drive and path before it will begin operation. Added - Errorlevel 5 to retain compatibility with BBS programs which use this as an indicator that a file is to be resumed. Added - Support for NON-ansi users. Added - Removed any attempt to send user output when a fossil is not found. Added - Internal archive identification by ID codes rather than the previous use of extension . (also allows testing of self-extracting archives) Added - The ability to preserve the AV in protected ZIP files. Added - The ability to fail files based on date. Added - Reporting of the BBS-name through the user-side ansi. Oct 27, 1992 - Ver 3.0 -No additions (Streamlined code and bugfixes) Bugfix - Internal archives which were not configured for, caused the system to choke with a runtime error. Fixed. Bugfix - A runtime error #6 was reported by a limited number of systems (using Share.exe). Repaired. Bugfix - A file failing the scan operation was still being reported as having failed scanning by "VER 1" (whoops). Bugfix - Some optimizing of code resulting in a smaller exe file. Nov 15, 1992 - Ver 4.0 - Emergency release to fix a problem with Scan Bugfix - The redirection of SCAN.EXE's output introduced in Version 2 was removed due to problems with detection errorlevels not being returned to the tester correctly under MS-DOS's command.com. Bugfix - The ansi screen now correctly identifies the version. Version 3 reported version 2 on the ansi screen. Feb 1, 1993 - Ver 5.0 - Standard update Added - Installation can now read settings from the previous version of THDPRO.EXE and incorporate them into the present version. (only version 4 is supported for this feature) Added - Support for the new PKZIP 204e self extracting files. As a result Version 5 absolutely requires PKZIP version 204e for the testing of "ZIP" archives. Added - A hack list can now be used (such as the "HACK REPORT") to avoid testing files with filenames that you do not want sent to your system. (files will fail but be saved) Added - The ability to supply a comport from the command line to override the default when being used on a multi-node system. Added - The use of comport "0" to suppress remote output. Added - THD ProScan now displays the name of the file being tested before testing begins as well as informing the sysop when testing has been completed. Bugfix - Internal delays were lengthened for those systems with fast computers and slow communications. Bugfix - Previous versions would choke on illegal filenames (fixed). Feb 12, 1993 - Ver 5.1 - Upgrade - Issued an upgrade which repaired an incorrect version number for version 5 as well as restoring the "syntax report". - Included THD ProScan's Terminal Assistant Version 2. Upgraded to avoid choking on directories and read only files. May 2, 1993 - Ver 6.0 - Standard update Bugfix - An old problem for RA sysops has been found and removed. In some very odd circumstances, RA users had a problem with THD ProScan deleting the wrong directory. Due to the rarity of the occurrence and the inability to reproduce the effect, it was assumed to be a strange conflict between the tester and RA. I did however manage to find a way to duplicate the occurrence and have removed the problem code. Bugfix - A change was made to allow simultaneous operation on two or more nodes. Previously this would cause problems with the testing and the logs. Bugfix - A problem with previous versions, whereby certain directory structures could cause a runtime error 5 while testing archives has been repaired. Bugfix - A user reported a Runtime error 103 when running THDPRO.EXE It was found that this error was caused by his deleting the directory in which THD expected to create his log files. When THD could not find the directory, it choked. It now tests for this condition and exits if unable to initialize the log file. Bugfix - Reportedly, Version 5 failed "Gif-lited" files during the GIFTEST run. Unconfirmed, but version 6 properly recognizes an errorlevel 10 exit from Giftest. Bugfix - Previous versions would fail valid archives if they did not have a proper file extension. Fixed. Added - Memory swapping while running the more "intense" tasks. Memory overhead will be reduced by about 48k during SQZ functions and SCAN functions. Memory reductions are compliments of TurboPower Software's EXECSWAP program. Added - Improved internal error checking to detect changes from original configuration. Added - Heuristic testing for viruses through the use of TBSCAN.EXE or F-PROT.EXE. Added - Installation can read settings from the previous version of THDPRO.EXE and incorporate them into the present version. (only versions 4 and 5 are supported for this feature). All future versions will support this feature for the two versions prior to itself. Added - Support for the new PKZIP 204g self extracting files. As a result Version 6 absolutely requires PKZIP version 204g for the testing of "ZIP" archives. (All versions between 1.10 and 2.04g are supported) Added - Support for the SQZ archive type. Added - "Move/Rename" suppression for those BBS programs that choke when files are renamed or moved. Added - The ability to substitute a non-zero comport for the local comport. Sysops who use a local logon to test files can now do so by telling THDPRO.EXE to substitute "0" when testing on a different comport, thereby avoiding remote output during logons to a specific node. Upgrade- Major code optimization and the introduction of encryption into the tester code resulting in a significantly smaller executable file. Change - The method used to identify the archives has been improved to increase the speed. Change - Previously, it was recommended to compress the executable file after installation. Due to the introduction of encryption into this release, that recommendation no longer holds. The tester will not work if the file is changed. Change - Included THD ProScan's Terminal Assistant Version 3 in the archive. Contains a fix for a problem when source and destination directories were the same as well as the ability to test directories other than the source configured internally. See THDTERM.DOC for details. May 9, 1993 - Ver 6.1 (Patch) Bugfix - The release of TBSCAN version 6 meant that the parameters needed to interact with it would need to be revised. This upgrade changed the parameters so that TBSCAN would not exit with an error on every run. Jun 9, 1993 - Ver 7.0 - Standard Update Bugfix - "GIF" and "TD0" files found internally to a valid archive type could cause version 6 to run forever. (fixed) Bugfix - PkZip 204 "AV" codes are now properly recognized. Bugfix - In some odd circumstances, version 6 could inadvertently remove the "current" directory instead of the temporary directory. (fixed) Change - PkZip's "AV" protection is no longer optional. Change - The parameters for TBSCAN version 6+ have been optimized. Support for earlier versions is no longer available. Added - The ability to supply a "list" of files to be removed from the archives. Added - Preservation of the Archive's original date and time. Change - MAJOR coding changes have resulted in reduced memory usage, increased speed, and the ability to search much farther than previous versions. Change - The order of drives selected for use can now be reversed or "rotated". (During the installation) Change - A change in the way TurboSoft's EXECSWAP program was utilized has resulted in the release of all but about 5 k of THDPRO.EXE's memory when running external tasks. All calls to external programs are now done through EXECSWAP. The Program itself uses about 75k of memory. Jun 12, 1993 - Patch to version 7.1 Released both an upgrade (patch) and a full release. Bugfix - Version 7 deleted all "GIF" and "TD0" files. fixed. Bugfix - Previous version would not run if they were made "read only". Fixed. Jul 1, 1993 - Ver 8.0 - standard update Bugfix - The ability to remove files from a "list" was rendered inoperable for "ZIP" and "ARJ" files. Fixed. Bugfix - Version 7 could leave orphaned log entries under some normal circumstances. This has been repaired. Bugfix - Some of the newer ARJ SFX files were not properly recognized. Fixed. Bugfix - Version 7 could, under some circumstances, become unable to remove it's temporary directory. Fixed. Bugfix - The add option of SQZ was including the paths to the added file. Fixed. SQZ files are now "updated" rather than "added" to avoid duplicates. Also the SQZ comment is now stripped before processing. Added - Version 8.0 now supports the HACKLIST "IDX" files directly as a list to be used for "hack checking". The "COL" file is still supported, as is the method described in the "THDPRO.DOC". Added - THD ProScan now supports the self extracting form of "HYP" files. Previously all Self extract data starting codes were hard coded into the EXE file. I have since found out how to read the executable header and now get the appropriate address from there. Change - TBSCAN command line parameters needed to be changed again to remain compatible with TBSCAN version 6.03. Change - The ARJ strip comment line was modified for compatibility with ARJ241. Change - The PKZIP "add" line has been modified to use maximum compression when adding loaders to archives. Change - Testing of SQZ archives will now be done on the same drive as the original archive whenever possible, due to SQZ.EXE experiencing difficulty when running across drives. Change - Memory swapping has been fully optimized. THD ProScan Version 8 leaves barely over 2k in memory when performing external tasks. Nov 1, 1993 - Ver 9.0 - standard update Bugfix - A rare error caused a few systems to hang (and/or report unwarranted errors) when testing some very specific files. Fixed. Bugfix - The name of the main archive was not included in the heuristic log if one of its imbedded archives contained suspicious code. Fixed. Bugfix - An error in the command line sent to TDCHECK caused valid TD0 files to fail the CRC test. Fixed. Added - Major addition of file conversions. 5 levels of conversions to choose from, as well as on-the-fly conversion for RG, TG and RA. (possibly the most complete file convertor available in ANY utility - dedicated or otherwise). Added - Description files can be imported into RemoteAccess 2.00, Telegard 2.7 File Data Bases directly by THDPRO.EXE (FILE_ID.DIZ, DESC.SDI, and DESC.SDN). In the case of viral detection, if this option is selected a message regarding the failure will be inserted instead (RA only). Added - Online help during installation. Added - Dos shell from installation. Added - Ability to put random and/or area-specific comments in archives as selected from a list. Added - Ability to put current date and/or time in user supplied file comments. Added - Ability for the sysop to customize the remote output through the use of ansi files (THDPRO.AN? and PAINSOFT.AN?). Providing an entire array of 21 possible output screens to be chosen from at random. Added - The ability to FORCE a single ansi output (PAINSOFT.ANS). Added - The ability to remove files from archives based on their CRC value. Added - The sysop may select to not automatically test files over a given size. If asked to test a file over the supplied size THDPRO will prompt the sysop for 5 seconds to press a key. If no key is pressed the file is not tested. Files skipped by this process will return the same errorlevel as a successful test. Change - SHARE is now detected and files opened in shared mode if found. If access to a file is denied, THDPRO.EXE will wait for up to 30 seconds for the other process to release the file before aborting. Change - THD ProScan will now finish in the same directory in which it started. Change - SCAN.EXE is no longer mandatory. Change - Heuristic failures can be considered virus infected. (optional if SCAN.EXE is used, mandatory if not) Change - Option to use any or all of the supported virus scanners. Change - Files original timestamp is optional (It can be kept or updated). Change - Output during virus scanning with F-Prot or TBScan now shows the remote what tester is being used. Change - Temporary directories are now chosen in a way which prohibits use of a directory that already exists. Change - Orphaned temp directories will be removed on the second day following their creation. Change - THDTERM4 is released with added support for users of FileDoor. Change - THDDEMO.COM has been modified to support testing of the sysop supplied ansi screens/interfaces. Dec 14, 1993 - Ver 9.1 - Bugfix release Bugfix - THD ProScan 9.0 had trouble with indexing some RemoteAccess 2.00 and 2.01 FDB's. Fixed. THD should now update the FDB correctly. Bugfix - Version 9.0 refused to add comments on "some" bbs setups. The problem was eventually traced to Share.exe and repaired. Bugfix - Version 9.0 would lock some systems when attempting to strip the comments from PAK and/or ARC packets. Fixed. Bugfix - A similar problem to that above was encountered by some systems with ARJ archives. This too has been fixed. Bugfix - THDPRO.EXE from version 9.0 ignored the AV when removing files by CRC value in ZIP files. Fixed. Bugfix - During the installation THDINSTL had severe difficulty dealing with "SCAN.EXE" when it was not in the dos path. Fixed. Bugfix - During installation, if the sysop were to use the new dos shell and change directories and/or drives, THDINSTL would experience a runtime error #2. Fixed. Bugfix - The settings as stated in the documents did not actually default to failing of heuristic tests when SCAN.EXE was not used. Fixed. Bugfix - Persons running Share.exe experienced a runtime error when attempting to use CRC mode. Fixed. Added - The /KO parameter which will cause THDPRO.EXE to not delete the original file in conversion mode. Added - Support for FILE_ID.DIZ importation into TG via an external file called THDPRO.DIZ. (See TG-RG.TXT for details) Added - The THDOPT environment variable which allows "some" minor aspects of the tester to be modified. (See newin9-1.txt) Added - "/C" option to THDDEMO. Use of this option when testing PAINSOFT.AN? files will allow you to scroll through the various colour schemes available for the header. (See THDFILES.TXT) Change - The colour of the identification lines (header) used during the display of PAINSOFT.AN? files are now configurable. See THDFILES.TXT for an explanation. Change - The identification line used during the display of PAINSOFT.AN? files now reads "CUSTOM ANSI INTERFACE" instead of "USER SUPPLIED ANSI INTERFACE". Change - Numerous minor changes have been made to the program in an effort to ease the potential problems running THD under a network environment. Change - The detection process for ARC and PAK has been modified to lessen the false detections. Change - The F-PROT command line has been modified for compatibility with F-PROT version 2.10. Change - TBSCAN uses the TBSCAN.LNG and TBSCAN.SIG files from it's current directory (if they are present). THD now changes directories before running TBSCAN. (TBAV609 fixed this) Change - TBSCAN version 6.08 also introduced a date checking procedure. If the files are older than 6 months, TBSCAN will prompt the sysop to press a key. Version 9.1 supplies the necessary switch to avoid this prompt. Change - Running "THDDOC.EXE X" will cause THDDOC to extract the document to a text file called THDDOC.TXT (overwriting any file by the same name) in the current directory. (For those of you who prefer text files to the executable supplied.) Apr 21, 1994 - Ver 10m beta - Public Beta (Interim release to tide the usership over until 10.0 can be released). Bugfix - The planned add-on support did not function correctly. (No add-ons were ever released.) Bugfix - Rejections of files by "date" has been corrected from version 9.1. Bugfix - Adding of archive comments has been repaired to add on every run. 9.1 experienced problem in some very specific circumstances. Added - Additional self checking to help ensure the integrity of the program. Added - Support for McAfee's VirusScan version 2.?.? via the THDOPT environment variable. Added - Best guess and newest file date options. Added - Three user definable conversion levels. Added - "Default" command line options. The ability to have THDPRO.EXE always process as if certain options had been supplied on the command line. Change - The internal configuration format was overhauled in the interest of speed. Change - The search routines were re-written to avoid detection of the volume label on systems running the OS/2 service pack. Change - The filemodes used by THD were changed so that THDPRO.EXE would run under RAMGR (which leaves file open when it shells out). Change - After loss of carrier, THDPRO.EXE now stops sending remote output. Change - A major overhaul of LHA handling. "Cloning" to be used in special circumstances. Change - THDTERM 5a beta. Avoids duplicate testing inherent with older versions and introduced the option to supply a comport other than "0". Aug 20, 1994 - Ver 10.0 - Major Upgrade (from 9.1) *** Note that changes made from the 10m beta are not listed here. All changes in that beta are considered to be part of 10.0 *** Added - Secure Mode - A mode in which THDPRO.EXE attempts to verify that changes to utilities it uses do not go unnoticed. A "breach" during secure mode will abort the test without attempting to use the modified file. Added - Support for UC2 and RAR archive formats. Conversions to these formats are also supported. Added - Third party programmer support through the use of TESTINFO.DAT, a new data file containing much information about the file tested. Added - Comment keywords for descriptions, newest/oldest file, newest/oldest date and author/product information. Added - The "/LA" (Log All) switch to THDPRO.EXE. Change - Major change to the testing/converting process. When space is available, all files will be expanded prior to virus scanning and conversions will take place without re-expanding all files. If this method fails, then THDPRO.EXE will revert to the old (one at a time) method at the cost of speed. Change - The SCAN.EXE command line is now compatible with the SCAN 2.x.x series. To use the 1.x.x series you must set the environment variable THDOPT=SC1. Change - BBS updates are no longer done by THDPRO.EXE. They are done by a new utility called THDPLUS.EXE. Change - The log directory "requirement". If THDPRO.EXE cannot locate the configured log directory, it will create its log in another directory (which is dependant on the users configuration). Change - Fossil routines have been optimized to avoid overrun with faster systems. Change - Ansi detection to not be "fooled" by "AVATAR" systems. Change - File descriptions have been modified to reflect reasons for failure in cases where THDPRO.EXE fails a file. Change - CRC failures are now subject to "Failed File Moving" if this option is set to normal. (previously these were left untouched.) Change - The "Waiting" message will now only be displayed as a result of a "share" related violation. Also the name of the file in conflict will be reported by this message. Change - Zip comments are now stripped internally by THDPRO.EXE. Change - The option to limit by date or age now ignores the dates of directories and uses only actual file dates. Change - Imbedded scanning is no longer reported due to its speed. The space it had previously occupied is replaced by Re-Archiving. Change - The method of drive detection in THDINSTL has been modified to be faster and avoid some access problems with some CD-ROM changers. Change - THDINSTL.EXE can be renamed to simplify installation on a network (or run THDINSTL.EXE /NET). See THDDOC for details. Mar 7, 1995 - Ver 11.0 - Emergency Release / bugfix Bugfix - The file failing by age and/or date was rendered inoperable in version 10.0. Fixed. Bugfix - Version 10.0 would initialize the comport if a fossil was detected (even if running in local mode). Fixed Bugfix - Files were not properly added during conversions. Bugfix - Conversion had difficulty with some files due to their names. This version now looks for these files and does not convert them. Bugfix - Conversion will fall back to the old method when non-convertible internal archives are found. Bugfix - The removal by list feature has been completely reworked for better performance. Bugfix - The /NFL (/NOFLOPPY) switch has been repaired and should now operate correctly. Bugfix - Logging of failed scans of non archive types has been corrected. Bugfix - Remote delays have been shortened. This should fix the output on many faster systems which previously may have "appeared" to be sending at 1200 BPS. Bugfix - THDPLUS has been completely reworked in reference to FILES.BBS. Bugfix - THDINSTL /NET (or NETINSTL) was adding "C:\" to all paths without drive letters. Fixed. Bugfix - The names of THDPRO.EXE's temporary subdirectories have been changed to avoid problems for those who utilize a country code other than 437. Bugfix - Removed the error I've come to know as THD ERROR=59. File not found. Bugfix - Fixed a share error which could occur when a file's size was over your maximum test size. Change - The program has been modified to avoid the "allfiles" warning given by TBSCAN.EXE version 6.32+. These newer versions will not work with THDPRO.EXE prior to version 11.0. Change - The ARJ security envelope is no longer allowed to verify itself except during the "CRC test" portion of testing. Change - Added the "/NOEMS" switch to the SCAN.EXE parameters for the 2 series of SCAN. This will was necessary to avoid window closures in Windows dos sessions. Added - CHGINFO.EXE which can change the path information in TESTINFO.DAT records to match the file's current location. Use is very specific, please see the documentation for details. Added - THDPRO.EXE and THDINSTL.EXE now reports the absence of SCAN's *.DAT files. Added - Support for RAR "AV"ed archives. THD now recognizes them and has the ability to create them via THDRAR=TRUE. Added - THDPLUS can now also extract the description for a file to an external text file. (THDPLUS /EXTRACT) As well, initial support has been added for T.A.G. 2.7, Telegard version 3.0 (working name) and for RemoteAccess version 2.5+ and for PCBoard 15+. many of the features in this version of THDPLUS are untested. It should be treated as a BETA for other than previously supported features. Nov 25, 1995 - Ver 12.0 - Standard upgrade / Introduction of the OS/2 native version. Bugfix - THDPLUS.EXE was modified to properly account for T.A.G. multinode setups. Bugfix - Fixed an error in the fossil routines which could cause some systems to lock up if carrier was dropped during the test process. Bugfix - Fixed the "adding" of files to AV'ed zip files during conversion. (Version 11.0 would corrupt the newly AV'ed archive.) Bugfix - GIF files could fail a virus scan due to an error in the SCAN.EXE command line. Valid GIF's are no longer scanned. Bugfix - CHGINFO could "miss" some directories when looking for FILES.BBS (Fixed). Bugfix - The four file dating options were inoperable in version 11.0 (fixed). Bugfix - The THD ERROR CODE = 58 which occurred on OS/2 systems "should" be repaired. If this is not the case, try the new OS/2 native version. Bugfix - Fixed the problem with Telegard 3.0 (2.99 Gamma) which resulted in duplicate entries when the "add" option was not specifically invoked. Entries may still be added to the TG3 FDB by using /ADD on the THDPRO.EXE command line or by SET THDOPT=ADD, however without one of these switches, THDPRO.EXE will only update existing entries. Change - Dropped internal support for SCAN version 1.?.? Change - The Hacklist feature will now recognize the BADFILES.CTL format. Change - Further improvements to the LHA cloning. Change - Archive diagnosis is more complete which allows for avoiding problems with multivolume archives as well as avoiding the password prompt on protected RAR archives. This change allow for some other minor improvements as well. Change - Files on drive "A" or drive "B" will always be treated as "read-only" allowing no changes to files resident on those drives. (This was in fact active in version 11.0 but not documented.) Change - "add" Gifspecs to the description. [RA only] Added - THDEXARC, which allows for addition of virus scanners and archive types not supported internally by THDPRO.EXE. This feature adds considerable functionality to the program. Added - Secure mode is now reported in the log and on the screen. Added - The ability to "envelope" non supported file types in an archive (convert specific non-archives to one of the supported archive types). Added - The ability to hit "P" during a dos process to cause that process to pause before returning to THDPRO.EXE (to view dos output before it disappears). When "P" is used to pause the screen, press any key to return control to THDPRO.EXE. Added - "/RO" to treat the test file as "read-only" (no changes what-so-ever to the original file). Added - "Deep" removal. (removal of files from subdirs and imbedded archives). This feature is available ONLY during conversion, and ONLY for those archive types which will actually be converted. Added - Support for UNP. If configured UNP will be run on every file. UNP expands compressed executable files to improve the chances of viral detection. This feature is NOT active during conversion since it will change the original files. Added - The ability for the user to limit the amount of disk space used during a test. Two such options exist. The ability to configure a minimum amount of free space or a maximum amount of space to be used for expansion. (See "Limits" note) Added - The ability for the user to limit the amount of time allowed for expansion of files. (See "Limits" note) Added - "/OV" switch to over-ride the new time and space limits. * Limits - The new limits are checked "only" after expansion of the archives and may not have any effect on archives which contain no imbedded archives. Space limits during testing of specific archive types (RAR - ARJ - LHA - ZIP) may be "calculated" prior to any expansion resulting in no expansion taking place if limits are "expected" to be exceeded. These limits can be ignored by us the the new "/OV" switch on the command line for manual testing. Dec 25, 1995 - Ver 12.1 - BugFix Bugfix - During conversion, version 12.0 would rename all imbedded archives back to their original name after conversion. This version correctly only renames those files with non-standard extensions. Bugfix - The expected errorlevel (EXIT_LEVEL) in the TESTINFO.DAT was not always recorded correctly. This cause programs which attempted to use this information to pass files which failed testing. Corrected. Bugfix - Corrected a typo in THDINSTL on the final screen where option "J" reported 'press "K" to modify'. Bugfix - On occasion, selecting one option from the final screens, upon completion of configuration of that option THDINSTL would automatically prompt for input in regard to another option (Fixed). Bugfix - THDPLUS when recording the "old" description from RA's FDB would sometimes record multiple descriptions (or portions of multiple descriptions) in addition to the correct description. Fixed. Bugfix - ZIP idenification has been modified again to avoid the long delays identifying corrupted ZIP archives. Bugfix - The OS/2 comport initialization was not working in all instances. The THDPORT=??? options did not "apparently" work where passing the file handle on the command line did. Corrected Bugfix - The T.A.G. structures did not "convert" well to the OS/2 version which resulted in a runtime error 100. The source of the problem has been found and corrected. Change - Ansi detection is now disabled if ANSI is forced via the THDOPT environment variable. Change - Formatting of the description for FILES.BBS is now only done if the description does NOT quailify as a valid FILE_ID.DIZ in respect to it's line length. Change - THDEXARC has been changed slightly so as to disallow changes to the parameter and path fields when dealing with "INTERNAL" archive types. Change - THDDEMO.EXE has been modified to more correctly display the ansi's on some ansi drivers (notably the one included with MS-DOS version 6.2x) which fail to properly translate the <esc>K sequence. Change - THDPLUS will not mark TESTINFO records processed when the TELEGARD v3 (2.99) BBS type is used unless THDPRO.EXE has processed the record twice or Telegard has marked the record as processed. This will allow TG sysops to keep THDPLUS in the same directory as THDPRO.EXE without TG being unable to find it. Change - The coding which surrounds the area known as THD ERROR = 58 has been completely reworked "again" in the hope of solving this problem for OS/2 users of the DOS version. Change - When creating archives from non-archives, THDPRO.EXE will now also "add" any files to the newly created archive which you have configured for adding to archives. Added - Added a BBS definition to support FILES.BBS type using the "|" (pipe) code to indicate extended description use. Added - A new option for THDOPT. SET THDOPT=ADDSPACE## will allow the addition of extra spaces to the front of the extended descriptions during FILES.BBS updates (## is the number of spaces to add). Added - In the OS/2 VERSION ONLY, the ability to set the priority level used by THDPRO.EXE during operation. Four switches /PR1, /PR2, /PR3 and /PR4. /PR1 is low priority and /PR4 is high priority. Added - A section of documentation regarding UNP usage was inadvertently missed. It is included as UNP.TXT. Added - Dupe Checking. Select to create a DUPE LIST in THDINTSL.EXE and thereafter use the /DC switch to check for files which have already been processed. (Records kept are via CRC/SIZE, so modified files of the same name which are not identical to previously tested files will not be considered dupes. Feb 28, 1996 - Ver 12.2 - BugFix (no additions or changes) Bugfix - An Error in THDPLUS messed (and sometimes missed) the FDB updating with the T.A.G. BBS type. Fixed Bugfix - An error in THDPLUS could cause problems when updating descriptions of files other than the last file in an RA FDB. Fixed. Bugfix - The File Date "Use File's upload date and time" was not functioning. Fixed. Bugfix - The docs refer to two options in regard to Failed File Moving. They incorrectly state the options as Active and Inactive. THDINSTL.EXE has been modified to match this wording. Bugfix - I finally managed to reproduce the "THD ERROR = 58" error and I "believe" I have solved it. (This one should get a prize for being the most elusive bug to date) Bugfix - A change in the handling of Zip files caused the "AV" flag to be reset in THDPRO.EXE during Convert-Only mode. This effectively resulted in THDPRO.EXE ignoring the "AV" when the /CO switch was used. Fixed. Bugfix - An error on the command line causes ZIP.EXE to not include subdirectories when rearchiving files. Fixed. Bugfix - THDINSTL.EXE incorrectly stated that removal of files by list supported wildcards within this list. THDPRO.EXE has been modified to allow wildcards in that list. Bugfix - Imbedded SFX archives were not being converted back to SFX archives. Instead they were being left in their native archive format. Fixed. Bugfix - THDEXARC.EXE's EXPORT function was inserting an "EXTERNAL" declaration when exporting virus scanners. This caused subsequent imports to fail. Fixed. Bugfix - An error in the switches used with RAR.EXE caused it to add the full path to any files it added to an archive. This has been corrected. Change - THDPRO.EXE has been modified slightly to handle THDEXARC records slightyl differently if the expansion and compression fields contain "N/A" (without the quotes). This will cause THDPRO.EXE to treat the "archiver" as a TEST-ONLY file (similar to GIFTEST) which in effect avoids attempts to expand or otherwise manipulate the file. (useful for tools like GFXCheck).
