- UNCR uncompresses files compressed with CRUNCH.
- :1
-
- Syntax UNCR [d:]<afn> [d:] [/Q | /C | /O]
-
- where [d:]<afn> is any filename (with optional drive spec). The second
- [d:] is an optional drive specifier where the output will be
- directed. If either "d:" is not specified, the default (logged)
- drive will be used. All input & output takes place in the cur-
- rent user area.
-
- Note that the resulting filename will be recreated from the name
- of the file that was originally crunched.
-
- It is not necessary that the file to be uncrunched have "Z" as
- the middle letter of the extension; an attempt will be made to
- uncrunch any filename explicitly specified. Note however that
- "UNCR *.*" will be internally converted to "UNCR *.?Z?" to facil-
- itate quickly uncrunching all crunched files in a mixed group.

-
- Options
-
- If used, the option should be last on the command line, and the "/" must
- be preceded by a space. Only one option may be selected.
-
- Q --> Quiet mode. "Quiets down" the amount of information sent to the
- console.
-
- C --> Confirm (tag) mode. Used for selective uncrunching. When used in
- conjunction with wildcard filespecs, this option causes the program
- to ask "Y/N" for each matching file. Only the files to which "Y" is
- responded will be uncrunched. Selecting this option causes the
- program to automatically ask for added confirmation if a pre-
- existing file is about to be overwritten, regardless of the program's
- configuration.
-
- O --> Overwrite without prompt. Suppresses the question "Destination file
- exists, overwrite?" from being issued every time the program is about
- to overwrite an old file with the same name as a new one.

- UNCR Notes
-
- a. Vs 2.3D1 fixes the problem of setting the !!!TIME&.DAT file to read-
- write when copying dates from files crunched with CRUNCH 2.3D. It also
- adds the feature of preserving the archive attribute of the !!!TIME&.DAT
- file.
-
- b. Vs 2.3D2 fixes the problem where UNCRUNCH restores the Last Access
- stamps of their output files from the headers of their CRUNCHed source
- files. Since the source file may not have been accessed for some time,
- the new copy may not appear to have been accessed today. UNCRUNCH now
- calls the DateStamper clock (if present) to set the access field of the
- output file to the current system time.
-
- c. Vs 2.3D3 fixes a problem of selecting the correct drive for the
- !!!TIME&.DAT file when the program is run on a non-ZCPR3 system. All
- changes are in the common routines module.
