-
- UNZIP dissolves MS-DOS .ZIP files.
-
- Version 1.2 (7/3/90) by David Goodenough.
- :1
- Syntax UNZIP {dir:}zipfile {dir:}{afn}
-
- Under ZCPR3 "dir" can be a DU or DIR spec; otherwise, just a drive. If no
- destination is given, member files are checked and listed. If a destination
- is given, member files are extracted if they match "afn" if given, otherwise
- the entire ZIPfile is extracted.
-
- You can now abort with ^C (and the partial output file, if any, will be
- closed and erased). The usage screen now responds to "//".

- UNZIP Notes - 1/2
-
- a. UNZIP still needs a lot of work. It really ought to be possible to
- extract member files selectively, but it's all or nothing at present.
- In addition, listing files should be a lot faster; checking CRC's in
- that mode seems unnecessary. Typing a member file to the screen would
- also be a nice enhancement. Maybe someone else will interested in going
- further. In the meantime, Steve Greenberg's ZIPDIR and Carson Wilson's
- ZTYPE can fill the gap.
-
- b. Version 1.5 updates (6/1/91, Howard Goldstein):
- - Fixed bug at WILDLP which was causing an output spec of "dir:" not to
- work correctly.
- - Corrected problems that were causing writes to disk when a non-
- matching member file was being skipped.
- - Changed "disk full" logic to close and erase partial output file and
- abort the program immediately.
- - Made several minor changes to allow assembly with ZMAC or M80.
- UNZIP Notes - 2/2
-
- c. Version 1.4 updates (5/16/91, Bruce Morgen):
- - Bug-fix in ZCPR3 detection code at "setusr"
- - Adds output filename specification with wildcards. Now the use of an
- output d:/dir: and/or an output filename will trigger extract mode.
- If the output filespec contains no wildcards (a d:/dir: alone is
- equivalent to "*.*"), UNZIP will now exit after the first extraction.
-
- d. Version 1.3 updates (5/12/91, Gene Pizzetta):
- - Some quick and dirty mods to make this utility more useful.
- - Now assembles with SLR's Z80ASM and it's a little more orderly.
