The QIO status OK shows that the QIO has succesfully started and that you
can expect an AST (if you requested one) and a valid IOSB when the operation
is done.
The 0 in the IOSB says the IO is not done. Hang around some more (debugger!)
and it will change\
Did yo mean to issue QIO or did you perhaps need QIOW?
Check out SYS$SYNCH?

you are not waiting when you should, or ask the system (QIOW) to do the wait
for you?
