- SAP v40 -- SORT AND PACK CP/M DISK DIRECTORY -- 09/17/84
-
- This CP/M utility reads the disk directory tracks, sorts the entries
- alphabetically and then rewrites them them back to the disk. All unused
- or erased areas on the directory tracks are reformatted with continuous
- 'E5' characters. This completely removes previous file names from the
- directory which have been deactivated. All files of zero length are de-
- leted with the with the exception of files beginning with "-". This
- supports labeling disks for the catalog program MCAT.) The program works
- with CP/M 1.4 and CP/M 2.2 but does not work with CP/M 3.0 or M/PM.
-
-
- Sorting the directory in this manner offers many advantages.
- Some of them are:
-
- 1) Allows 'DIR' to show an alphabetized listing.
- 2) Eliminates potential problems with "UNERASE" programs by
- removing programs with a similar name that have been
- previously deactivated.
- 3) Speeds up access via 'SD' and other special programs.
- 4) Assists on working directly on the disk with 'DU', etc.
- 5) Removes files from the disk directory that somebody else
- could recover. (The data is still out there somewhere).
-
- TO USE:
-
- A>SAP40 B: B: in this case indicate the desired
- disk to be sorted and repacked. If
- not included, the logged on drive
- will be sorted.

- 09/17/84 Added 'Previously sorted' statement that was included in v37
- v40 but got dropped from v38 when the Shell-Metnzer sort was put
- in. It still rewrites the directory even if previously
- sorted, to insure erased programs at end of directory are
- properly cleared. - Irv Hoff
-
- 07/27/84 Corrected sorting of last directory entry.
- v39
-
- 10/16/83 Now using a Shell-Metzner sort which speeds the sorting time
- v38 considerably, especially on large directories. (SFK)
-
- 07/27/83 Shows an error flag for MP/M and CP/M+ both. Rewrites the
- v37 directory even if previously sorted, to insure erased pro-
- grams at end of directory are properly cleared.
