Release to Public Domain ============================= DCATxx.EXE and DCATxx.DOC are released to the public domain, without restrictions of any kind. The source code is not available. B. Warning ============ WARNING! This program is capable of magnetically writing information on disks. I have tested it as carefully as I know how, and so have others, with no ill effects. However, as with any such program, please take a few basic precautions. Create a few floppy disks for test purposes, and back up your hard disk. Run CHKDSK and any other diagnostic programs you may have BEFORE you run DCAT, then again AFTER running DCAT and exercising its features, especially the re-label feature. Please don't let this warning "turn you off" on DCAT, I believe it should be common practice with ANY new program, commercial, shareware, or otherwise. It runs on my system with no problems that I can see, and has been tested under DOS 2.0. However, it may have other effects on other machines I don't know about yet. Once a few dozen people report using it without any problems (if that many ever run it), I'll be a lot more comfortable. I run a Toshiba T3100/20, which is an IBM-AT compatible machine, with DOS 3.2, Vcache, Sidekick, and about a dozen other TSR's. C. Quick Start ================ Warning! (If you have been using DCAT02 or earlier beta test versions, you should (once more) erase and re-create your entire master catalog. Sorry.) Preferred usage is to place DCAT on your hard disk (usually C:), anywhere in your normal path, RENamed as you like (I use DC.EXE). Call up the program in the usual way, and you will be presented with some information, along with the prompt to insert a disk in drive A:. Just hit the <space> bar, and repeat for a few disks, then exit with <Esc>. Then, look in your root directory using any lister (Vern Buerg's LIST62A highly recommended (shareware, $15)), and you will find a two new files, named DCAT.CAT and DCAT.BAK. As you might suppose, DCAT.BAK will always contain the "previous version". DCAT.CAT will first list each disk label and space available, one per line. DCAT.CAT will then list each file found and disk label where found, one per line. Subsequent runs will update the catalog as you might expect. D. Introduction ================= DCATxx (xx is the version number) is intended primarily as a program to catalog floppy disks, so that any given file may be found as quickly as possible from a bunch of floppies. It will also assist in "housekeeping" on such floppies, allowing the user to determine how many copies of a file exist, and where they are located. It is fast, simple, and convenient, without many of the "bells and whistles" of other MS-DOS programs. It will scan all sub-directories on the cataloged disk. It will maintain the master catalog in pure ASCII (upper or lower case) text, allowing the use of other programs and tricks with that catalog. The master catalog is maintained in one file, with two parts. The first part is a list of disks, with free space remaining, each on one line. The second part is a list of filenames, time/date, filesize, disk volume label, and sub- directory found, each file on one line, with its data. Example: VolumeLabel Space deakin020 491520 free main 6463488 free |- End disk listing -| Filename.Ext mm/dd/yy hh:mm:ss Size VolumeLabel Path\Path\... |----------| |------| |------||------| |---------| |---------------> abort.txt 02/05/88 18:08:28 15232 main \tap addendum 01/01/88 12:00:00 3265 main \pr datetest.c 11/01/87 23:17:36 959 main \turboc\source dc.bak 03/05/88 13:24:14 18380 main \turboc dc.c 03/05/88 01:01:42 18181 deakin020 \ dc.c 03/05/88 13:37:44 16458 main \ dc.c 03/04/88 15:26:12 17493 deakin020 \subdir1 dc.c 03/04/88 15:26:12 17493 deakin020 \subdir1\subdir1a dc.c 03/05/88 13:37:44 16458 main \turboc dc.c 03/05/88 01:01:42 18181 main \turboc\source dc.exe 03/04/88 16:12:10 18974 deakin020 \ dc.exe 03/04/88 16:12:10 18974 deakin020 \subdir1 dc.exe 03/04/88 16:12:10 18974 deakin020 \subdir1\subdir1a dc.exe 03/05/88 13:37:58 19174 main \turboc dc.obj 03/04/88 16:12:08 10951 deakin020 \ dc.obj 03/04/88 16:12:08 10951 deakin020 \subdir1 dc.obj 03/04/88 16:12:08 10951 deakin020 \subdir1\subdir1a dc.obj 03/05/88 13:37:56 11215 main \turboc dcat.arc 12/23/87 22:47:22 30027 main \turboc\source dcat.asm 09/26/87 23:34:04 3200 main \optasm dcat.bak 03/05/88 01:56:42 6230 main \ z80asm.com 07/01/87 23:05:48 22528 main \z80cpm z80mu.exe 12/08/85 17:00:00 96518 main \z80cpm zaptap.inf 01/01/88 01:01:00 5632 main \tap Note the file is maintained in FILENAME.EXT order first, SUB-DIRECTORY order second, and VOLUME LABEL order third. This may appear a bit odd at first, as you might think it should appear in the displayed order, left to right. However, if I put the sub-dir information in the second column where you might expect it, that column would either have to be 80 characters wide to accommodate the longest possible path name, OR the columns would be "ragged", which would be most undesirable. When DCAT loads, it determines the amount of memory available to it, and determines (and tells you) how many files per disk it can handle. My system has about 430,000 bytes of RAM free after all my TSR's are loaded, and this allows just over 8,000 files per disk (absolute maximum is 32,000). The size of the master catalog is limited only by disk space. E. Command Line Options ========================= For those wishing to use DCAT in a different way, there are several command line options. If you elect to use these, I suggest you either set up a BAT (Batch) file to do it the same way, every time, or even better, a CED (or PCED) SYNonym. (CED is public domain, PCED is a commercial product, both by Chris Dunford, Cove Software Group.) If you do use options, and try to remember them, you will almost certainly end up with different catalog files scattered all over the place, possibly with information from an unintended disk. There is no way to "merge" such files. Command line options may be entered in any order, or omitted. They must be separated by one or more spaces. DCAT scans the command line, checking the syntax of each "group of characters" for proper matches. A quick example of a full-blown command line: C: > dcat a: -c:\misc\catalog ufx ^^^^ ^^ ^^^^^^^^^^^^^^^^ ^^^ |||| || |||||||||||||||| ||| |||| || |||||||||||||||| +++-- Letter options |||| || |||||||||+++++++------ Catalog name |||| || ||||++++-------------- Sub-dir name |||| || +++------------------- Drive specification |||| ++----------------------- Catalog this disk ++++-------------------------- Program name The following command line would produce exactly the same result: C: > dcat xfu -c:\misc\catalog a: 1. Disk to be cataloged ========================= This command line parameter tells DCAT where to find the disk to be added to the catalog, and must consist of a letter, A through F (upper or lower case), followed immediately by a colon, in the usual MS-DOS manner. Valid examples: C:> DCAT A: <-- normal usage C:> DCAT C: <-- can do this, from root only C:> dcat f: <-- lower case ok, too 2. Disk, path & file name for master catalog ============================================== (Note: Previous versions required the "backslash" to identify the disk and sub-directory where the catalog file is to be placed. This has been changed to the leading "-" (minus). This command line parameter tells DCAT where to place the master catalog. The user can specify a disk drive, a path, and a filename. It must have a leading "minus" (-) in order for DCAT to recognize the command. That leading minus will NOT be used as part of the filename. Valid examples: C:> dcat -\catalog This would force the filename to be CATALOG.CAT(the ".cat" extent is added automatically), into the root directory of the C: drive. C:> dcat -catalog Careful! This means put it in the "current sub- directory", from wherever you happen to call DCAT. C:> dcat -d:\subdir1\subdir2\catalog This would put CATALOG.CAT on drive D:, with the path \subdir1\subdir2 3. Letter Options =================== If DCAT finds a command line group that does NOT match the syntax for the first two described above, it assumes you are specifying one of the command line option letters U, F, or X, described here. Superfluous letters are simply ignored. Valid examples: C:> dcat u <-- all upper case, C:> dcat uf <-- and ask for new labels, C:> dcat ufx <-- and make a cross-reference file. (U) Upper or lower case catalog listing DCAT defaults to keep the master catalog in all lower case. If you prefer, you may use this option to force all upper case. If you decide you want "the other case", just re-catalog one floppy with or without the U option letter, and the entire catalog will be re- written. The ORDER is always as if all alpha characters are actually in upper case, regardless of the case chosen for the catalog. This is necessary to handle filenames or labels with odd, non-alpha characters. (X) Create cross-reference listing when done Disabled function, at this writing. (F) Force new label query on each disk This option tells DCAT to stop on every single disk and ask for a new volume label, even if there is already one on the disk. A simple <cr> will tell DCAT the existing label should be kept. This is of benefit to the initial setup of your master catalog, and later when adding a group of new disks. Note that if there is no volume label at all on the disk, DCAT will automatically prompt for a label, regardless of how it was called, and will not continue until a valid label is entered and written to the disk. Note this may create a problem if you have a factory master you wish to catalog, with no volume label, and write-protected. It will be necessary to "un-protect" it long enough to write a volume label, either with DCAT, or some other program. A better procedure is to make a copy of that master, add a volume label, and catalog that. F. Usage suggestions ====================== In some ways, DCAT will allow you to do things in a much less organized manner, while keeping you better organized. However, to do this, it is necessary to do a little organization first! Let us consider the manner in which most folks organize their floppies without a cataloging program. Most seem to gravitate towards sticking a paper label on the disk jacket, with a general title or comment as to what type of programs are on that disk. If you program in BASIC, you might have one labeled "Working BASIC programs", another "BASIC data files", etc. I find this terribly wasteful of disk space, as one seldom-used disk might go for months with only a few files, while you might have to have three or four (or more) "Word-Processing Data Files" disks, some full, some not, perhaps with some loose grouping. Labels are difficult or impossible to peel off, and end up a mess, eventually having little relationship to the contents of the disk. Think about the way MS-DOS handles files. You certainly don't care if a text file gets put on a track right next to a program, you let DOS take care of all those details. Why not treat your collection of floppies in a similar manner? Whether you have 20, or 200, why not treat the whole bunch as just one big "blob" of data, and let an easier system take care of the dirty details? I realize this will be a radical idea to many, and can hear the howls now "but I've ALWAYS kept my <whatever> files on a separate disk!" DCAT can help you there, too, but I think there's a better way. For any effective use of DCAT, you will need to develop and use a reasonably systematic method of labeling disks, with the magnetic volume label also clearly displayed on the disk jacket. A simple system of four digit numbers, like "0001", "0002", etc. will do nicely, and means you'll NEVER have to re- label disks again. Warning! DON'T write MAGNETIC volume labels as "1,2,....9,10,11,12", however! That would sort as: 1 11 12 2 3 which most folks would consider undesirable. There's nothing wrong with putting "1" on the PAPER label of disk "0001", of course. However, DCAT permits any volume label, so it's up to you. There MUST be some way to relate the volume label to the physical disk. It doesn't do you much good to have a volume label of PA2342SLT, and have the Toshiba factory paper label say only "Master System Disk". With that, you've got to remember what it means, and that's a bummer. I suggest you fool around with DCAT a little bit, see how it works, then give some thought to a systematic way of labeling your disks in some manner that provides a direct mental connection between the paper label and the magnetic volume label written into the disk directory. This is a crucial, absolute requirement! DCAT may be copied to any drive, any subdirectory, and renamed as needed. I run it from my \ms subdir, where all my system files and utilities are located, and I call it DC.EXE. Note there is a command line option for (F)orce, and also a (F)orce option while actually running DCAT. If you use the command line option, DCAT will automatically stop and ask for a new label on each disk. If you are in the midst of a cataloging operation, did not specify the "F" option, and realize you wish to re-label just one disk, you may hit "F" instead of <space>, and DCAT will prompt you for a new label for just that disk. (Of minor interest is that ANY key will make DCAT "go", not just the space bar and the "F" key.) Unlike previous programs under CP/M, DCAT does not require the creation of a zero-length file with special characters. Instead, it uses the capability under MS-DOS to have a "volume label" written magnetically on the disk. Any legal characters for a volume label may be used, and no special characters are required. WARNING: A volume label is ALWAYS required. Volume labels should be unique, or all files on multiple disks will be listed under the same volume label, sort of defeating the purpose of DCAT. The first time DCAT is run, it will create its own datafile, as needed. You can, if you wish, have several catalog data files, in different sub- directories, or with different names, although that's likely to get confusing, if overdone. The master catalog and the backup file are closed and updated after every single disk. During operation, the catalog data file is read, left unchanged and a scratch file is created. Only upon successful close of that file does the previous data file get written to <filename>.BAK, and the scratch file RENamed to <filename>.CAT. As a result, you will normally have the current catalog, and its predecessor when DCAT is done, normally named DCAT.CAT and DCAT.BAK. Even a power failure at the most critical moment will leave a good catalog, either in <catfile>.CAT or <catfile>.BAK. These are pure ASCII text files, and can be looked at with any editor. Be VERY careful about editing, as the program expects to find certain things like spacing, format, separator lines, etc. Any MANUAL edit that alters order, spacing, or virtually anything about the file will corrupt it, and subsequent catalog operations by DCAT will only increase the errors. Once corrupted, the file cannot be recovered. I STRONGLY suggest you ONLY delete whole lines if you edit the file, and DO NOT delete or alter the lines like: VolumeLabel Space |- End disk listing -| <- not even this blank line! Filename.Ext mm/dd/yy hh:mm:ss Size VolumeLabel Path\Path\... |----------| |------| |------||------| |---------| |---------------> It is much safer use a "lister" program that cannot alter the file, and let DCAT itself do all the alterations. DCAT was designed to be used with Vern Buerg's superb LIST62a program, available as shareware ($15). That program will allow you to scan the list, look for specific text, and find whatever you need, using the (F)ind and (A)gain commands. There are others that will do the job, but I know of none so nice. It is one of the most heavily used programs on my own system. Note the columnar layout of the catalog file. If you wish, it is suitable for a variety of purposes. It can be sorted in many different ways, for example, by disk volume label. To do this, COPY the catalog file (normally DCAT.CAT) to a file with another name, use any editor to "clip" the first section out, then sort on column 40 (with left-most column being 1). With similar modest effort, the catalog file might be loaded into a dBASE DBF file, or some other data-base program's data format. On my system, I also have a SYNonym called "cat" which looks like: ced syn cat "list \dcat.cat" With this, from any DOS prompt, anywhere in the system, I can just type "cat<cr>", and look at my master catalog of disks. The same effect can be had with a BAT file, of course. You'd create a text file called CAT.BAT in your normal path, with the following line: list \dcat.cat There is currently no easy way totally to delete an entire disk from the master catalog. In my opinion, this will rarely be required, because even though you delete all files from a disk, you still want the disk listed in the catalog file, showing it as having maximum "Space Free". If you must totally delete it, the easiest way to do so is to erase all files from the disk you wish to delete, run DCAT on it to remove all the files from the catalog, then simply edit the catalog file to remove the one line that contains the volume label and free space remaining. Alternatively, a macro editor could be used to search out all occurrences of the volume label and delete any line on which it is found, but that could also delete a filename containing the same characters, if you're not careful. If you want to delete a volume from the catalog, and you do not wish to delete all files from the disk in order to run DCAT on it, you can also temporarily label a blank disk with the same name, and run DCAT on that. Ok, let's assume you have DCATxx.ARC, DCAT.EXE, and DCAT.DOC in your current directory as you read this, and you have temporarily labeled a few disks with masking tape, and "0001", "0002", etc., and cataloged them, just for fun. You think you'd like to archive just DCATxx.ARC, and wonder which disk has enough space. Check the size of DCATxx.ARC, then look at the catalog's first section, scan down until you find a disk with "just enough" space, grab that disk by number (absolutely uncaring what else might be on it), copy DCATxx.ARC to it, call up DCAT, hit <space> <esc>, and you're DONE. The file is archived and cataloged in less time than it took you to read this paragraph! (A side benefit is that using DCAT in the suggested manner will lead to much more effecient usage of your floppy disks, with most of them having only a little space remaining, then a few with increasing space, followed by all the rest with maximum space free.) Having done that, you delete the ARC file from your hard disk, but find you'd like to pass DCAT along to a friend, in the original ARC file. You call up your catalog with LIST62A, use the <F>ind command on "dc", then <A>gain until you come to DCATxx.ARC. Looking on that line, you see it is on disk 0018, and in what subdirectory (if you use them on floppies, I don't). Grab the disk with "0018" (or "18") on the jacket, and you've got it, right now. Now let's say you're one of my long-suffering beta testers, and you've got "dc*.*" files all over the place, just like I do. Call up LIST DCAT.CAT again, <F>ind "dc", and take a look. Fish out all the floppies with "dc<anything>" on them, DEL DC*.*, and you KNOW you're starting "clean". (Of course, you then have the option of DELeting all these LATEST files, forgetting you ever heard of DCAT, and REALLY "starting clean"!) DCAT scans the floppy very quickly, and the moment that scan is done, you are free to remove that floppy and insert the next one, even if DCAT is still writing the new or updated information to the catalog file. A bell and prompt tells you exactly when you can do this, and with a little practice, you'll be able to catalog floppy disks just as fast as you can stuff 'em in the drive. (Of course, DON'T try this during the really strange case of writing the catalog datafile on the same floppy being cataloged!). G. Credits ============ DCAT is 100% original coding in Turbo C from scratch, by me, except for a few lines by Dennis Vallianos in the disk volume re-labeling function. However, I would be less than honest if I did not give credit to the people and programs which led up to it. According to Ward Christensen, "sometime in the late 1970's", he wrote a CP/M program he called FMAP that would, among other things, produce a sorted directory to a disk file. From this was born the idea of a "master" catalog program. Since CP/M had no provision for volume labels, Ward also had the idea of creating a zero-length file under CP/M, with the initial character "-", so that it would sort to the top of the list. FMAP created the list, UCAT updated it, and CAT was for searching the list. Ward remembers writing, but probably did not release a program he called KAT, which could do a much faster binary search on initial characters. According to much later documentation in an MS-DOS variant (NCAT), in early 1980, Lewis Moseley, Jr. wrote a program combining these functions, and called it NEWCAT. Irv Hoff remembers "some fellow in a trailer camp near Georgia" working on this program, and that he thinks it was called NCAT at the time. That may, or may not have been Moseley. Irv then took the program, cleaned it up, made it more automatic, made it capable of handling any number of sorted filenames, and renamed it MCAT, eventually ending up with MCAT45, which remains, in my opinion, the classic disk catalog program for CP/M-80. In about 1982, Dennis Vallianos translated NEWCAT into 8088 assembler language, and called that NCAT. The one problem with that program was that it did not create a list of disks, with free space remaining on each, a critical need, in my opinion. On April 7, 1984, Peter A. Polansky, of Dolgeville NY, took the source code from Irv's MCAT, and translated it to CP/M-86, calling it MCAT86-1. It did not produce a list of disks and free space either. I was quite distressed at the huge size, clumsiness, and "rampant featuritis" I found in the other disk catalog programs in the DOS world, so decided to "roll my own", with only the options I wanted. I have named it DCAT, for "Disk CATaloger". I started in assembler, but about that time, Borland came out with the superb Turbo C compiler, so I decided to use that, learning a little about C in the process. (Wow, did I ever!) My deepest thanks: To Ward Christensen 76703,302, who started it all. To Irv Hoff 76701,117, whose efforts in CP/M public domain programming are a legend, and an inspiration to us all. DCAT is patterned very closely after MCAT45, although I have never seen the source code for that program. To Dennis Vallianos 70406,1163 for his assistance these many years, on a variety of computer-related matters, for his encouragement, for his pushing me to try Turbo C, and for specific advice and comments on DCAT. I have cursed him (under my breath) as much as I have praised him publicly, but I've learned a good deal as a result of his efforts, and in spite of my own limitations. To Bill Snyder 70425,115 and Phil Tobias 74055,530 for encouragement, testing, suggestions and assistance. To Mike Rubenstien and Pete Becker on Borland's BPROGB for several very helpful messages getting me over a number of humps in learning a little about Turbo C. H. Future Upgrades ==================== You'll note the (X) "Cross-reference" command is disabled. I have not yet decided exactly how to present the information, user input is requested for "the next version", please. I know how to do it, I just can't think of any satisfactory method of displaying the information. About the best I can think of at the moment is: dc.c 03/05/88 01:01:42 18181 deakin020 \ 03/05/88 13:37:44 16458 main \ 03/04/88 15:26:12 17493 deakin020 \subdir1 03/04/88 15:26:12 17493 deakin020 \subdir1\subdir1a 03/05/88 13:37:44 16458 main \turboc 03/05/88 01:01:42 18181 main \turboc\source dc.exe 03/04/88 16:12:10 18974 deakin020 \ 03/04/88 16:12:10 18974 deakin020 \subdir1 03/04/88 16:12:10 18974 deakin020 \subdir1\subdir1a 03/05/88 13:37:58 19174 main \turboc 03/04/88 16:12:08 10951 deakin020 \ dc.obj 03/04/88 16:12:08 10951 deakin020 \subdir1 03/04/88 16:12:08 10951 deakin020 \subdir1\subdir1a 03/05/88 13:37:56 11215 main \turboc I am considering further command line options to make DCAT do a sort on other fields, producing a separate file of results. User input requested. Again, I know how to program it, I just don't need any other formats myself, and have no idea what you might have in mind. I. Modification history ========================= March 8, 1988 DCAT03 John Deakin ================================= Added a blank line to separate the two portion of the catalog file. Total re-write and cleanup of the source code, many functions re-done. Added progress reporting to say "Rev: " on files with the same name, same sub-dir and same volume, but with a different time/date. Previous versions said "Del: ", then "Add: ", which was a bit disconcerting. Totally re-wrote sort and merge routines. Converted from Tiny memory model to Compact. Finally! Added full date, time, size and sub-directory information to catalog file. Minor cleanup of opening screen, on catalog file display. Added progress reporting during catalog operation, will delete this in future versions, as I gain confidence that it is not bombing any systems. Fixed problem where if DCAT was invoked from a subdirectory, and told to catalog the same disk from which invoked, it would start in the current sub- directory and work "down" only. It will now ALWAYS catalog from the root directory of ANY drive, and will end up back on the drive, and in the sub- directory from which invoked. (Unless interrupted with ^C, in which case it will end up logged onto whatever drive, and in whatever sub-dir was being cataloged when halted.) Changed command line syntax, to use the more familiar "minus" sign to identify the disk/drive/path of the catalog file, instead of the visually confusing backslash or worse, the double backslash. Should have been this way from the start. Changed memory allocations and compiler options so that uninitialized pointers do not take up space in the EXE file. Added code to determine maximum number of disk files per disk. Cleaned up the logic in the merge_label area, reducing file size a little. Changed all internal operation to work with all upper case at all times. If U option is NOT selected, conversion to lower case is done only just before output to the screen or to the catalog file. This results in exactly the same file order regardless of case, and also allows changing case of the entire catalog file. Fixed bug introduced in DCAT02, if no label on disk, a <cr> is entered at the label prompt, then <esc> was hit, disk was cataloged under a blank label. February 10, 1988 DCAT02 John Deakin ===================================== Fixed bug causing master catalog corruption if any of the five characters ( [ ] ^ \ _ ) between the upper and lower case ASCII set are used in filenames or disk labels. Increase maximum files per cataloged disk to 10000 from 1000, which was used during development and forgotten. Added error trapping to detect more than 10000 files per disk. Complete re-write of this DOC file. February 4, 1988 DCAT01 First full release. John Deakin ========================================================== Calling this one DCAT01, removing all restrictions, releasing to public domain. Added subdirectory traversal, will now catalog every file, in every subdirectory, using recursion. When a file is in two or more subdirectories on the same disk, it will show up as two entries in the master catalog, and in the cross-reference. Fixed bug that added trailing spaces to master catalog entries. Completely re-did logic (again) for merging directory entries with catalog entries. January 1, 1988 (approximate date) Fifth release. John Deakin =============================================================== Cleaned up disk volume re-labeling routines, with assistance from Dennis Vallianos. No more deleting, so DOS 2.0 block removed. Cleaned up command line parsing, parameters can now be entered in any order, with minimum key strokes. Cleaned up logic of merging labels, merging files.
