Abend in WAIT4CMD

[gehlert]

Finally, I'm ready to try JZOS in the STC environment.

Unfortunately, I get an abend 4039, reason code 0, shortly after registering the MVS command callback (see partial dump below).

Environment is z/OS 1.6.

By the way, I get the same abend when trying to run my test program (which just registers the callback and waits for commands) from an initiator.

Any help very much appreciated...

Thx, Uli

I think I figured it out... I thought you had to call ZUtil.establishMvsCommandWaiter() yourself, and that's what I did in my test program. Re-reading the documentation, I found that JZOS does this for you automatically.

Dropped that call to establishMvsCommandWaiter(), and now it runs ok in batch (not sure about STC but can't check until tomorrow).
