Re: Writing multiple CD volumes for the AS/400?

Hi Brad,

Maybe I misunderstood something -- I had the impression your product mimics
a tape drive.  In which case the AS400 only sees what you let it see, and if
you unzip the data before passing it to the AS400, how would it know it's
zipped?

What exactly does your product do again?
