Sigh! I wish that IBM would train its developers to exploit the platforms they're writing to and not give excuses; TSO had TGET NOWAIT long before MVS-OE, and there is no need to simultaneously wait for terminal input and output.

Hello Lionel, TSO OMVS design issue - the RUNNING/INPUT switch is to simulate TTY on a 3270 block mode terminal. for reference, and possible solution:- https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.bpxa400/misout.htm At times you may find that the status indicator changes to INPUT before you have received any or all of your output. Don't worry—the shell is producing output and storing it in a buffer. Just press the Refresh function key and the shell will display more output on your screen. (If you don't have a Refresh function key, you can press a <Clear> key, <PA2>, or <PA3>.) The reason for this behavior is that TSO/VTAM provides no way to wait for keyboard input and TTY output at the same time under TSO. On the z/OS UNIX System Services Web site, there is some code (poll.c) that lets an OMVS user remain in RUNNING mode indefinitely. This improves usability, but it can have a significant performance impact if many people use it. You can download the code by going to the Tips section: http://www-03.ibm.com/systems/z/os/zos/features/unix/ Regards Bruce On Sat, 27 Jun 2020 10:12:55 -0500, Lionel B Dyck <[email protected]> wrote: >I'm running a rexx script under the OMVS shell and have an anomaly that I >need help with. <snip> > > >When there are more (I don't know what that number is yet but in excess of >30 but less than 100) the shell input status changes from RUNNING to INPUT >and will not proceed until I hit ENTER.
