RE: AS400 PKZIP: was: Tape question -- MIDRANGE-L

It would stop me.  I was not aware of that limitation.  That would seem to
disqualify the product.  How can that be?

Richard,

be aware that the ASi PKZIP product for the 400 has record length
constraints.  It will ZIP a 1000 byte record, but when you unzip it you'll
only get I think 128bytes of your record...the remainder ends up in teh
bit bucket...  This is a BIG show stopper for alot of folks...
