I looked at Chapter 2. OMVS, a 3270 terminal interface to the z/OS shell in z/OS: UNIX System Services User's Guide and didn't see anything about requiring an OMVS segment. It's possible that you need an OMVS segment to use the OMVS command, but that's certainly not implied by the functions for RXX under a Unix shell. > And it was done as a function package, so SIGNAL ON NOTREADY is not supported. The ANSI specifications call for returning an empty string rather than raising a signal. But I wonder whether IBM would accept an RFE to allow external to raise a signal. -- Shmuel (Seymour J.)

Feels political: Conway's Law? I believe the author was a UNIX-oriented developer, perhaps daunted by the co-requisite for allocation. But that was done for cp(1) and a few other functions: https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.bpxa500/usmd.htm And it was done as a function package, so SIGNAL ON NOTREADY is not supported. A programmer might kludge SYSCALL PIPE and cp to get a streamable file file descriptor file. I understand that compiled Rexx supports ANSI stream I/O for Classic data sets but not for UNIX files. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
