[comp.os.cpm] crunched files

marwood@DMC-CRC.ARPA.UUCP (03/15/87)

Ralph Hyre asks about the significance of .?z? files.
These files are crunched files, which use a data compression algorithm which 
generally produces smaller compressed files than the "squeezed" .?Q? files.    
The means to "crunch" and "uncrunch" may be found in PD:<CPM.SQUSQ>
CRUNCH23.LBR.1 on SIMTEL20.   Crunched files should not be confused with 
.AZM files which are used as source files by several Z80 assemblers, e.g.
Z80MR.  Non-crunched .?Z? files crunch into .ZZZ files.

Is there a version of uncrunch that runs on Unix systems?

The latest version of UNCRunch for Unix is now available from SIMTEL20
as:

Filename			Type	 Bytes	 CRC

Directory PD:<UNIX.SQ-USQ>
UNCR231D.C.1			ASCII	 13664  591EH

This is a LZW uncruncher, written by Frank Prindle, which is
compatible with Z-80 CP/M program CRUNCH 2.3.
