- IMPORTANT: If you should create an error because of the drive door
- open, be aware that choosing <A>bort as an option will
- return you to DOS. The obvious choice is to close the
- drive door and <R>etry. <F>ail will return you to PmCat
- with things as they were before the error. ( <I>gnore
- has never struck me as a viable option when DOS informs
- of an error ... you may know better ... <grin>
-
-
- Earlier versions of PmCat requested all available memory on a system
- (up to 640K), when it was run. That approach left NO DOS MEMORY
- available for the shell option which we have installed in this version.
- We must decide at the time we compile PmCat just how much memory a user
- will require ... and obviously that is quite impossible.
-
- We regretfully had to restrict the memory available in this distribution
- version of PmCat to 250K in order to ensure all of the features would
- work on as many configurations of computers as possible and that the
- above situation didn't occur without warning, causing the user to
- suspect the integrity of PmCat.
-
- The accompanying documentation details how we will handle this situation.
-
- In spite of the necessary memory restrictions, PmCat is still capable
- of extremely powerful cataloging functions. Even though the 250K
- available in memory does limit the number of files to 1000 - 6000
- (fully commented vs no comments at all ... approximately), it is
- extremely easy to create multiple catalogs that are accessed from
- withing PmCat, and the addition of the DOS SHELL function allows you
- to look at files, delete, move, copy, etc. on the floppy disks and
- immediately update without having to leave PmCat and reload it each
- time you just want to "check-out something".
-
- And in the case that you just want maximum memory for your catalog
- and don't care about the DOS SHELL feature, you may obtain a custom
- configured copy of PmCat for your own use as detailed in the documentation
- that accompanies this package.
-
- Work is proceding on making more aesthetically pleasing and useful hardcopy
- formatting available in PmCat. The printing of diskette labels is also
- very seriously under consideration. Both of these options will require a
- great deal of time and effort however, and there is no way to accurately
- predict when they might be ready. Rest assured we do consider these
- features essential.
-
- Don't forget to turn off your 'perf-skip' feature on your printer, if
- you have it ... the docs contain formfeeds.
-
- Also, to accomodate the longer names for the ASSIGN PATH as VOLUME
- feature, it was necessary to increase the size of every record by
- 8 bytes. The result is that the path, if greater than 12 bytes will
- not be displayed fully, but it will be read properly ... although
- you will not be able to view it with PmCat. If you have a specific
- need for a longer PATH, I can custom configure a copy for you ... but
- bear in mind that for each 1 character increase (it is currently 12)
- you will loose memory at the rate of the number of files in your
- catalog. (E.g, if you increase it by 8, up to 20 characters, and
- have a catalog with 2000 files, your memory will be decreased by
- approximately 16,000 bytes.) That 2000 file catalog would take up
- about 40 bytes per file + 80 bytes/file for comments without extending
- the size of the filename to 20. Perhaps this is enough explanation
- for you to visualize how much memory you may require and which
- memory configuration would fit most closely.
