In case anyone is interested in this, the result of my experiment is Yes, an assembler program running AMODE=31,RMODE=31 can in fact do QSAM I/O to a TSO terminal, provided the I/O buffers are in 24-bit storage. I've got the DCB, the exit list, and a DCB ABEND exit stub (and no other macros or code) in 24-bit storage. The DCBE is in 31-bit storage and specifies RMODE31=NONE (for documentation only; it's the default) which puts the buffers below the line.

Looking at Gil's note, I got to wondering whether perhaps the first assertion (about areas [buffers?] above the line) in "The support for areas above the line is not provided for the following devices: TSO terminal ... For the above devices, issue macros other than OPEN and CLOSE in 24-bit addressing mode." is true but the second assertion (about macros in 24-bit mode) is false (no longer true?). I think I may try moving everything except the DCBs and exit stubs above the line but keeping the buffers below the line and see if it still works with terminal output. (I can live without terminal input.) ---------------------------------------------------------------------- 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
