SMP/E routinely invokes HLASM and Binder which therefore must reside in authorized libraries. But they don't routinely require APF, so they're AC(0). In fact, programers should be free to invoke them in unauthorized environments.

I know that I can cause HLASM to program check by supplying an invalid PARM (or could when I tried a few years ago). I don't know that this can be leveraged into an integrity threat, but it's at least suspicionable. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
