Well, I did try using just the WAKEUP RESET (which changes the SMSG to
ON from SMSG IUCV), but I still missed the first IUCV MSG.

You might try 'WAKEUP RESET' just before you do the 'WAKEUP +0 (IUCVMSG'
(You didn't say, but assuming you tried this and it worked?). You
should also end your routine with WAKEUP RESET (just before you restore
msg values - RESET does a SET MSG ON, which may not be what it was).
It's not clear in the doc - but I 'think' doing a RESET clears IUCV..

Good points. I've had the problem with MSG/SMSGs still in limbo and the
WAKEUP receives those first. Is there a way to clear these prior to
issuing the WAKEUP (or sending the SMSG)?

Another couple of points --
- Since you can't control who might send a message to you when - you
probably want to loop until there are no more rc=5. It could be a msg
from another user is stacked in IUCV.
- DESBUF is kind of brute force -- it wipes out the stack -- and there
could conceivably be things stacked and needed by whatever calls you.
Better to do a 'MAKEBUF';buf=rc ... and then 'DROPBUF' buf ...
then you only drop the things in your 'own' stack.. and you aren't
affected by what may already be in the stack for whatever called you.

Try turning the 'SET MSG IUCV' to 'WAKEUP +0 (IUCVMSG' .. I think this
gets WAKEUP ready - and also issues the SET MSG IUCV. The example
under 'HELP WAKEUP' shows it done this way and I seem to recall needing
to do it in something I'd written.

I don't quite understand why I'm missing the first IUCV MSG sent to my
virtual machine after an IPL. The basics of this program is:
1) Send a SMSG to VMUTIL of 'RUOKAY'
2) VMUTIL, if alive, will send back a MSG response
"IMOKAY"
3) If the proper response is received the RC is set to
zero, all other cases it's set to 1
