Then the ECB would already be posted and the WAIT ECBLIST would be satisfied immediately. It is a consideration for all such routines, and not a big deal, unless the coder is stupid enough to reset the ECB before the WAIT, rather than after. > Is there a need for persistent storage accessible by both Rexx and Assembler? Well, the actual parameter passed by the Rexx is continuously accessible to the Assembler. It is of course possible to access any Rexx variable from assembler, but I see no need. If I understand your question, the answer is No. > Is there a way for the operator to send SIGINT (Unix "Modify")? Can Rexx > catch it? Not if it's vaccinated. <g> Seriously, no idea.

Is there a need for persistent storage accessible by both Rexx and Assembler? Is there a way for the operator to send SIGINT (Unix "Modify")? Can Rexx catch it? -- 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
