Bugs and enhancements in previous versions of WSSINDEX Enhancements are listed under the first version in which they appear, bugs (hopefully) under the last. Version numbers should be interpreted as decimal numbers, i.e. 3.1 and 3.10 are identi- cal. If the first digit of the version number changes, it means a major upgrade; if the second digit changes, it is a significant upgrade; and if the third digit changes, it means a bug correc- tion. However, if there are enhancements ready when a bug correction release becomes necessary, they will also be included. If you discover a program bug, don't assume that someone else will report it. This is especially true for the Rainbow version since I don't test it on a Rainbow. Your comments are also welcome on program features (or lack thereof) and the quality of the documentation. The various utility routines will usually be updated with each release because they share subroutines with WSSINDEX. There may not be any obvious change in function, and in this case I some- times forget to change the version number. Versions 1.01 through 1.03 1. Various minor bugs and a fatal error (destroys database) when removing or replacing disks. These versions were not widely circulated, but if you have one of them, you should upgrade. Version 1.04 None reported. Version1.05 1. Added I option and warning on exit if file not saved 2. First attempt at a Rainbow version (1.05R). Add comments section didn't work (different function keys and ANSI sup- port). Couldn't read back a saved database because read routine didn't expect a 5 character version number. Version 1.06 1. Changed disk save code to create .BAK files instead of over- writing old file. 2. Rainbow version needs special handling for delete key. Some copies of version 1.06R claim to be 1.05R. 3. Line counting and pause at end of page logic fail if there are comments. 4. Core used for comments was not freed when zapping an in-core database before Getting a database from disk. Version 2.00 1. Major revision. Add-comments section completely redone, added category field and view file option. Added configura- tion file, file selection options when printing, expanded sort options, interception of control-c, and made number of files limit configurable (had been fixed at 3000). 2. Disk file format change; upward compatibility retained. 3. First edition of this .DOC file. 4. Cursor positioning was not always correct when advancing to the next file in the add-comments menu, and if not corrected (say by hitting CR twice), added comment could be lost. 5. Print-to-disk operations did not check for disk-full errors. 6. A disk removal or replacement operation following a sort messed up the sort pointers (resorting corrected the prob- lem, and the database could be saved to disk without prob- lems). Version 2.01 (and 2.01R and 2.01V) 1. Copy comment/category functions changed to copy from exist- ing comment/category rather than copy buffer to allow easier updating of a previously commented file. 2. First upgraded Rainbow release (there never was a 2.00R). 3. Category information could be lower case, but the match string for selections is forced to upper case and thus could never match. 4. If configured to not create .BAK files, the program would not allow you to overwrite an old file with the same name, after asking if it was OK to do so (introduced in 2.00). 5. The seconds field of the file date has always been wrong. Version 2.10 (and 2.10V, 2.10R was never distributed) 1. Added predefined categories and "B" option. An error will be reported when reading old configuration files because the predefined categories are absent, but all other information is retrieved correctly. Made all string matches case insen- sitive. 2. "B" option didn't always work, reported some backed up files as not backed up. Version 2.11 (and 2.11R and 2.11V) 1. Fixed "B" option. 2. View file option crashes with a FREE error when reading an unlabeled disk. Version 2.2 1. Changed format of configuration file, some options will be assigned garbage values if you restore an old configuration file. Added option to suppress selected fields when print- ing. Added default options for most input prompts. Fixed core left function for greater than 64K remaining. Deleted display of configuration info on initial entry if a configu- ration file is found. Made default limits on database size dependent on free core available. 2. Get database option doesn't warn you if there is a changed database already in core. 3. Errors in reading configuration files were not always de- tected. 4. Printer line width logic sometimes failed and gave an extra line if you printed comments but not categories. Version 3.0 enhancements 1. Added support for .ARC files, WSSICNF and WSSIDIR environ- ment variables, default file names changed by appropriate input/output to file, word-tabbing and insert mode indicator in add-comments menu, enhanced selecting for comment and category. Shortened the .EXE file by removing unused float- ing point routines. Version 3.0 bugs, fixed in 3.1 2. The configuration variable WSSICNF had to specify a complete file name, it was not completed from WSSINDEX.CNF. 3. Core used for categories was not freed when zapping an in- core database before Getting a database from disk. This slowed operations as well as wasting space. Version 3.1 enhancements 1. Added support for color monitors and alternate PF key ar- rangements. Added truncation option for long lines and duplicate flagging option. Expanded exception list from 10 to 20. Made order of month/day/year printing configurable. Added option to index alternately from two drives. Made some code improvements to speed up indexing. Added control- F, Qand V optionsfor quickeraccess tocommonly usedfunctions. 2. First release of CUSTPRNT printing utility. Version 3.1 bugs, fixed in 3.11 3. If a disk with a volume label or subdirectory name contain- ing a null or a line feed was indexed, the saved database either could not be loaded, or loaded incorrectly. Such a label or name would only be expected on a damaged disk (but two users reported this bug in the same week). I have successfully recovered databases damaged by this bug; regis- tered users may contact WSS Division of DDC for assistance. Version 3.11 bugs, fixed in 3.12 1. The ANSI escape sequence used to select black & white (col- or) should have been ESC [=2h (ESC [=3h), but in one place the equal sign was omitted. Color selection would work when you went through the color selection menu, but failed other- wise. On some Dec Rainbows, or using some ANSI.SYS replace- ments, the incorrect sequence locked the keyboard. And the Rainbow doesn't support the ANSI color selection commands anyway. 2. The Rainbow versions of WSSMERGE and CUSTPRNT both called IBM-specific routines which crash on the Rainbow. 3. A bug in the code which read the disk directories (intro- duced in version 3.1) could have several manifestations, the most common being a program crash with a FREE error, but also bad subdirectory names could be reported. This bug was hard to trigger, and depended very much on previous opera- tions and how many subdirectories were on the disk. Version 3.12 enhancements 1. Added ^A and ^D options, dd-Mon-yy date style, and MORE pause for screen output. Changed default page length to 60 (had been 66). Converted menu to two columns to use less screen space. 2. First release of comment import routine. Version 3.12 bugs, fixed in 3.20 3. The flag indicating whether or not to use color was not included in the configuration file. (Why didn't anyone complain about this?) The date printing style was also not saved in the configuration file. 4. Date printing style yy/mm/dd came out dd/mm/yy. Version 3.2 enhancements 1. Added selection option to exclude ARC file members. Made carriage return mean unsorted or no selection options when printing, etc. Sorting is now done after selecting, so sorts will be faster. Doing sorts after selecting means that the option to sort without printing is no longer useful so it has been removed. The add comments function will now ask for sort options (and automatically reuse the same options if a new file spec is entered when you exhaust the list of files matching a previous file spec). Added option to enter mixed case volume names for rename and remove options. 2. Added ability to assign comments to volumes and subdirec- tories. Old databases must be run through a conversion utility before this option can be used. 3. Added option to list directory when an unlabeled disk is indexed. Added printer left margin parameter to configura- tion. Changed print header to include name of database file, and made headers optional in disk output. Made color selection display use cursor keys to move between fields. Added code to detect whether ANSI.SYS or equivalent is installed. 4. Split this document off from the main DOC file. 5. Added disk label and disk cover functions to CUSTPRNT. Version 3.20 bugs, fixed in 3.21 6. Left margin indenting is done twice to the main title of a CUSTPRNT multi-column listing, and not at all to the bottom line of a disk cover. Any form feeds from CUSTPRNT appear after the left margin indent, which might cause problems with some printers. 7. Volume names to remove from the database which are entered from the keyboard (R then E) are not forced to uppercase. 8. Trailing blanks added by the user were not removed from newly added comments. 9. The date printing style saved in the configuration file was not always used, and if the saved style was 01-Jan-80, the month number was printed instead of the day number in a volume listing. Any pass through the configuration change routine corrected the problem. 10.Control-A (dummy entry) option seriously broken in version 3.2 only. Databases created using this option can not be reloaded. Version 3.21 enhancements 1. Primarily a bug correction release, but also some enhance- ments which were ready when the control-A problem was re- ported. 2. All screen I/O is now done in "raw" mode with control-c and control-s checking at the end of each line instead of after every character. Screen output should be at least 20% faster, and menus will not be messed up by hitting control-c at the wrong time. This is reset on exit, but if you manage to crash the program, the screen will be left in raw mode. 3. Added U and ^U options to list duplicate or unique files, and selection option for only ARC files and ARC members. 4. END key in add-comments now moves cursor to the end of the comment or category being entered; control-end deletes text from cursor to end. 5. Added more general *text option for selecting comments, categories and other string items. Sorts on comments and categories are now case insensitive. 6. Predefined category change screen now gives option to save configuration if any category strings have been changed. 7. ^D option now allows a path specification rather than de- faulting to the first indexing drive. Version 3.21 bugs, fixed in 3.22 8. Selecting by disk name failed for names shorter than 11 characters because blanks were not appended. 9. Volume list to the screen used configured printer width rather than screen width when printing comments. 10.Comments for disk volumes listed with the V option usually came out shuffled. Version 3.22 enhancements: none, bug correction release only. Version 3.22 bugs, fixed in 3.30 1. A ^D directory listing which specified a path would produce no output if the most recent print task had been interrupted with ^C. 2. The test for ANSI.SYS caused problems on some machines, including incorrectly claiming that the machine was not responding to ANSI sequences, feeding the cursor position report to the routine which wanted a yes/no answer, or hanging the system. 3. The predefined category definition screen and the add- comments screen used an ANSI sequence to clear from the cursor position to the end of the screen. Some versions of ANSI.SYS and some replacements do not support this sequence. It might be ignored, or it might clear the entire screen. The fix is to use direct video writes. 4. If a print to disk operation found that the requested file name already existed, and the user elected not to overwrite the existing file, the program would crash with a "WRITE" error. 5. WSSINDEX included the dummy .ID entries in the count of files on a disk. (IDADD did not.) 6. WSSINDEX did not check for file names with embedded blanks, and while DOS allows such names, you can't manipulate them easily with DOS commands. Version 3.30 enhancements 1. Switched from Computer Innovations C86 to Turbo-C version 1.5 which produces a significantly smaller executable file. 2. A major rewrite of all the screen I/O code to allow direct video writes to MDA or CGA memory for speed, leaving a DOS calls option for incompatible systems. (The screen I/O code rewrite was done before I bought Turbo-C, so I did not use any of the Turbo-C routines which might have accomplished the same thing.) 3. Cleaned up the internal structure of the configuration file, which had gotten very messy since new things were just tacked onto the end to preserve compatibility. Old configu- ration files cannot be used. The new structure allows easier modifications, so future changes should not invali- date old configuration files. 4. Changed the memory allocation scheme so that fixed length items are allocated during initial setup rather than as the database is read or created. This means that there will appear to be less available memory before a database is loaded, but this space will be used up much more slowly. Essentially, only subdirectory names, comments and catego- ries will take additional space. The net effect is that databases can hold more files in the same memory. 5. Added five file rejection options to the standard selection options. Arbitrarily long lists of wildcard file names to select or reject can now be entered. The list of configured exceptions can also be arbitrarily long. 6. Moved the screen location of the subdirectory name in the add-comments menu. In the old location, a sufficiently long name could wrap to the next line and mess up the display. 7. File categories entered with Alt-letter now are added to the end of the current new category (along with a comma and a space). This effectively allows multiple categories for a file; to select one such category, use the *string form for the match string. 8. Command line arguments can now be used to specify the con- figuration and database file names. 9. Added option to "push" to DOS. 10.Added code to catch some disk errors without triggering an "Abort, Retry, Ignore?" message by first reading a sector by INT 25h. Thanks to Robert L. Hummel for a writing a PC Magazine column which suggested this trick. Version 3.30 bugs, fixed in 3.31 (comment import utility only) 11.The comment import utility usually failed to match files with 3 letter extensions if the input file had fn.ext style names. Version 3.31 enhancements: none, bug correction release only Version 3.31 bugs, fixed in 3.32 1. The logical flags indicating whether to extract information from ARC files and whether to use the alternate PF key arrangement were interchanged by the configuration read routine. 2. If doing screen I/O with DOS calls, adding or removing several disks from the database would scroll the menu off the top of the screen, and it would not be restored when the operation completed. 3. If configured to do screen I/O with DOS calls in raw mode, WSSINDEX and CUSTPRNT would leave the screen in cooked mode on exit, while WSIMPORT would leave it in raw mode. All 3 now leave the screen in the same mode as they found it. Version 3.32 enhancements: none, bug correction release only Version 3.32 bugs, fixed in 3.33 1. If configured to print everything on one line, truncate long lines, and print categories, the () normally surrounding the category would be printed even if this overflowed the al- lowed line length. This would wrap to the next line and mess up the line counting. 2. At startup, an ANSI escape sequence is output to select the default black & white mode. If the configuration was then set to use color, the B&W mode selection was never undone, and the system would be in this mode when WSSINDEX or CUSTPRNT terminated. Changed to set color mode on exit if color was used. Version 3.33 enhancements: none, bug correction release only Version 3.33 bugs, fixed in 3.34 1. Removing a disk from a database or reindexing a disk may clobber subdirectory information in the database (if there are any subdirectories on indexed disks). This bug was introduced in version 3.30. All registered users were mailed a warning after this bug was discovered, and those who had received defective versions from me were shipped free upgrades. I'm not sure how hard it would be to repair a database damaged by this bug (but I bet I'll find out). Version 3.34 enhancements: none, bug correction release only Version 3.34 bugs, fixed in 3.35 1. If using DOS calls for video output, directing any output to other than the screen would cause single character screen output to later be sent to the wrong place. Version 3.35 enhancements: none, bug correction release only Version 3.35 bugs, fixed in 3.36 1. The custom print utility repeated the first volume name listed rather than the proper one. 2. The custom print utility tried to print one extra line on each page, but the output routine knew better and so one file would be missing at each page break. 3. When printing disk covers, the characters for the right hand side of the box were usually printed too far to the right for the header lines. 4. When printing disk covers for multiple disks with subdirec- tories, the subdirectory rather than the disk name was used as the primary sort key which caused different subdirec- tories to appear on different covers. 4. When calling DOS to index or label a disk, the reserved fields in the extended FCB were not set to any particular value. This doesn't bother my operating system, but some of my documentation claims that these fields must be zero. Version 3.36 enhancements 1. Hex FF, if found in a file name or volume label when index- ing, is now translated to a blank. This character is nasty because it displays as a blank, but would not be matched by a blank when selecting, etc. Version 3.36 bugs, fixed in 3.37 1. When exporting and printing comments or categories, the entry for a file without a comment or category would be 2 consecutive quotes, which will confuse most import routines. Also, no allowance was made for quotes embedded in these database fields. 2. The code to check whether a disk was ready failed for disk partitions bigger than 32 MB under Compaq DOS 3.31 because Compaq changed the interface to the absolute disk read interrupt (they had to because the old interface could not specify more than 32 MB). Version 3.37 enhancements: none, bug correction release only Version 3.37 bugs, fixed in 3.38 1. Not exactly a bug, but the code used to test for disk-ready interacted with a bug found in many versions of DOS to cause DOS to not read the boot sector to determine whether disks being indexed were single or double sided. (Probably also a similar problem with 8 vs 9 sector disks.) I'm not sure how common this DOS bug is, but it is not limited to obscure machines. (In fact, it may only be absent in obscure ma- chines like mine.) 2. Disk output without headers in CUSTPRNT tried to write everything to an in-core buffer only one page long, over- writing things and crashing. 3. Volume labels were counted as files in "V" option listings. 4. DOS-calls video mode used the clear-to-end-of-screen se- quence which is not supported by all versions of ANSI.SYS. 5. If using direct video writes without also having ANSI.SYS loaded, escape sequences used to set defaults would appear on the screen at startup and on exit. They still appear, but now only momentarily before the screen is cleared. Version 3.38 enhancements 1. Added ^R option to redraw add-comments screen if it gets messed up. 2. All configuration items now have defaults which can be selected by hitting return. 3. Configuration routine now rejects a request for zero subdi- rectories (used to accept it and claim not enough memory). 4. Increased allowed number of characters in CUSTPRNT printer initialization strings to 50. Version 3.38 bugs, fixed in 4.0 1. Duplicate/unique processing, when supposedly checking for matching date and time, only checked the time. The backup check looked only at the date, not the time. 2. Any use of the add-comments screen set the flag indicating that the database had been changed, even if no changes were actually entered. Version 4.0 enhancements 1. A major change with this release is that the shareware version is a limited demo; full version is only available to purchasers. 2. Combined most of the DOC files into a single manual with page numbers and a table of contents. 3. Added support for other library formats: LBR, ZIP, ZOO, PAK, PKA, ARK and the ability to extract comments from libraries. 4. Added option to page backward and forward when listing files or volumes to the screen. 5. Made the response to some input errors more forgiving - prompt for re-input rather than dropping back to the main menu. 6. Added new option ^G to get configuration file and matching database, and command line specification of = for database name to perform similar function on startup. 7. Added new option ^R to erase in-memory database. 8. Made default database and configuration file names indepen- dent of any change of current directory which might be done when pushed to DOS with the S option. Also changed the user prompt while in a DOS shell to remind user how to get back to WSSINDEX or CUSTPRNT. 9. Added option to quote all fields when exporting (required by Lotus 1-2-3 and possibly other database programs). 10.Added command line parametersto most of the utilityroutines. 11.When checking for backups, subdirectory selection now ap- plies only to the disk being checked for backup so that it is easy to check part of a hard disk for backups. 12.Added new environment variable WSSDISP which specifies the default screen output method. 13.First release of utility SPLIT which divides a WSSINDEX- format database into two smaller databases. 14.New "zippy" search option which looks for character strings anywhere in file name, extension, comment or category. Available as a substitute for find from main menu or as another selection option. 15.Output routines now properly handle line counting when a subdirectory name is long enough to cause line wrap. 16.Printer definition files now accept ascii, octal, decimal or hexadecimal values. 17.Added option to select sort order when printing disk covers. Version 4.0 bugs, fixed in 4.01 (Rainbow only except for SPLIT) 1. The database splitting utility (version 1.0) would fail if the first disk in the input database had any subdirectories, and also often if there were comments or categories. Fixed in version 1.01. 2. The Rainbow version of the configuration routine always set DOS-calls video mode after reading a configuration file so fast video could only be used by resetting the configuration each time the program was invoked. Version 4.01 enhancements: none, bug correction release only Version 4.0,4.01 bugs, fixed in 4.02 1. Paging backwards through a volume listing didn't work right. 2. If an ARC file had garbage appended to it, such as might happen if it were padded to a multiple of 512 bytes when transferred by modem, and if some but not all files had comments in the archive, Wssindex could interpret the ap- pended garbage as comments. If the garbage included a newline character, the database would no longer be readable. I can easily repair any databases damaged this way. 3. The B-option could be confused if backups had equal or later dates but earlier times, and would report files as not being backed up, when actually they were backed up. 4. When exporting with all strings quoted, library file names and missing comments and categories were not quoted. Version 4.02 enhancements 1. Added code to demo version to check for a user password set by an environment variable so that registered users can "unlock" demo releases obtained from other sources. 2. Added suppport for the LHarc file compression utility. Version 4.02 bugs, fixed in 4.03 1. Multiple-page volume listings directed to printer or disk lacked form feeds between pages. When printing volume lists, it was necessary to hit return twice to tell the program that the printer was ready. 2. Exit from the add-comments menu was a little awkward when files were selected by name only. You had to hit escape if you didn't want to enter another file spec, but the message didn't tell you this. 3. When printing disk covers, CUSTPRNT would ask for the number of blank lines to insert when the first sort key changed, but this key is always the volume name, and when this chang- es a new cover is started. Changed to look at the first user-entered key after the two required keys. Version 4.03 enhancements 1. Changed the name "predefined categories" to "keyboard mac- ros" to more accurately reflect their function. No change in how they work. 2. Changed the way wildcard specifications are interpreted when searching for files. FOO* is now equivalent to FOO*.*; to match only files with no extension, use FOO*. instead. 3. File and volume lists to the screen now recognize HOME (PF1 for Rainbow) as meaning go to beginning. 4. Added support for the LARC file compression utility. Version 4.03R bugs, fixed in 4.04R (Rainbow only) 1. Hitting Q to get out of a file or volume listing failed. 2. It was possible to completely mess up the screen display, either by using the push to DOS option and doing anything which scrolled the screen, or by hitting control-c in some places. Version 4.04R enhancements: none, bug correction release only Version 4.03, 4.04R bugs, fixed in 4.05 1. Due to a bug in the Turbo C compiler, the N (rename) option was broken in the demo version only: if the new disk name was less than 11 characters long, it would be padded with a few hundred characters from the opening screen, starting with a blank, rather than just with blanks. All routines in the package have been recompiled with the "merge duplicate strings" compiler option disabled in case there were other unnoticed problems caused by the same compiler bug. Version 4.05 enhancements: none, bug correction release only Version 4.05 bugs, fixed in 5.0 1. Selection of archive files and members didn't select the archive files. 2. High-bit ascii characters in comments and categories were not handled well in any of the routines; loading a database would strip them off. 3. Comments could not be extracted from ARC files written by PAK. Version 5.0 enhancements 1. The user interface was completely rewritten. Multiple menus were added, along with mouse support. Many new configura- tion options were added. Unfortunately, this overflowed the expansion space which had been allowed in the configuration file format, so the format had to be changed and old con- figuration files cannot be used. The new format is designed to allow further expansion. 2. Not exactly an enhancement, but there will be a price in- crease effective Nov. 1, 1990. 3. Printer page specifications by width, length, and left, top, and bottom margins. Option to use form feeds or line ad- vance at end of page. 4. Indexing options to control whether to make .ID entries, ask before replacing a disk, add auto-comments, add auto-catego- ries, ask before extracting archive information, include hidden files, or include subdirectory tree in dummy entries. 5. Checksum disk image to verify program integrity. 6. Configurable default selection and sorting options. 7. Listings have configurable number of blank lines between and after headings, file names may be in FN.EXT format, field width used for subdirectory name, archive file name and comments or categories may limited, comments may be printed before or after categories, delimiters around archive file name and category may be changed. 8. When entering file names for database, configuration file, etc., the prompt gives the complete default drive and path; these may be edited. Filling in of defaults values is only done when the program first starts up. There is no longer any problem with using extensions on subdirectory names. 9. File specs for database searching and configured exceptions may be entered and edited in full-screen mode. The last- entered set of specifications is remembered the next time the full-screen editor is entered. 10.Disk volume sorts may be by the numeric part of the volume name, regardless of where the number appears. 11.File selection may now start from a previously selected subset. 12.Selection by date range now defaults to no limit, and day, month, and year are entered in the same order as used for date printing. 13.Added internal key buffering so that control-s and control-c will be recognized even if an unprocessed keystroke has been made. 14.Indexing of ZIP files was speeded up by reading the central directories at the end of each ZIP file rather than the local directories scattered throughout the files. Text prepended to a ZIP file, which PKZIP ignores, is now also ignored by Wssindex. Version 5.0 bugs, fixed in 5.01 1. The auto-commenting option only worked when a disk was re- indexed. 2. The trigger letter C was used twice in the indexing menu. 3. The comment import routine did not recognize escape when prompting for a comment file name. Version 5.01 enhancements: none, bug correction release only
