Yes, I really need to write an IBM mainframe format tape. So, it
sounds like I have to try the tape on the IBM mainframe to see if it
can read it. Does the IBM mainframe read variable block format?
I also need to be able to read EBCDIC tapes coming from an IBM
mainframe on an UNIX system. Do you know any software that runs on
UNIX (preferably - Solaris box) that can read an EBCDIC tape that has
an IBM label? I am willing to purchase the software.
Thanks,
