Hi all,

I got the source for Info-Zip and compiled it (which didn't fix anything) 
but it did allow me to debug things and I found that the allocate was not 
getting the only allowed "zero" return code.  Further checking allowed me 
to discover that there appears to be a problem with C routines under LE 
when allocating a dataset if the module(s) in question are loaded from the 
shadow copy of a linklist dataset and not the base copy.  Changing ZIP to 
be in the base allowed normal operation.  I went back and tested with the 
original module and it also works in that base configuration.

I don't see that this will be a problem for people using "real" dasd, just 
the ADCD users (like me).  

I tested zip on our 2066 under z/os V1.7 (with "real" dasd on a shark and 
it functioned fine.  I rebuilt the ADCD and included the module in the 
base and it workd fine for both Z/os 1.6 and 1.7.  When I rebuilt again 
and left it off the base so that it would be loaded from the shadow copy 
and again it fails.

Hopefully this will help someone in the future if they run into the same 
problem on their ADCD system.

Brian
