Subject: Re: Old Info-zip program

< I know the Info-zip program is very old, year 2000, but I need a FREE 
compression program that checks the consistency of the compressed file when it 
is uncompressed. 

info-zip works fine on one of our systems (z/OS 1.13 USS).

There is another possibility to zip a file. You could use jar, the Java archive 
tool. A JAR file is just a zip file.


< I was using TRSMAIN, but I found out the hard way that a tersed file can be 
truncated and TRSMAIN doesn't issue an error message. 

Ooops. This I would classify as a bug. Did you open a PMR?
