I'd say that the first step is to run a trace and find out what your terminal simulator is actually sending when you click on ATTENTION. Ideally, it will be the aid for PA1, exactly one time, but life is full of surprises.
Does your ATTENTION key work as expected with other applications? -- Shmuel (Seymour J.)

The goal was just to write an extremely primitive counter-tester, which the user can interrupt after X seconds to see what counting-performance had been achieved. When I run the program and then press my 3270 emulator attention key, the program just ends instead of the attention handler gaining control. The console log shows a SLIP TRAP X33E and X13E were matched. MVS system codes SA38-0665-30 says for 33E : "During processing of a DETACH macro that specified a STAE=YES operand, the system found that the specified subtask had not completed processing" code 13E is : "The task that created a subtask issued a DETACH macro for that subtask, specifying STAE=NO before the subtask ended. I ASSume the "subtask" is my test program ?? And the "task" is TSO ?? Or maybe not :/ How do I just get the ON ATTENTION handler to work ?
