Thanks to everyone for explaining how this is done. If I'm not wrong, the commercial products use their own DASD format. I thought that using the fake tape that Flex (and Hercules) use would be better.
As always, my ideas are horribly difficult. I'll try to come up with something within my grasp (at least for the first few).

There is at least one commercial product that does what you want - "redirects" the I/O to a real DASD device, and it works pretty much the same as in my footnote [1] below. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
