[comp.lang.asm370] VMCF

BRUCE@UMDD.BITNET (Bruce Crabill) (01/13/88)

Make sure your External interrupt buffer is large enough.  SENDX needs a
larger than default one.  Make sure you blank fill the VMCPUSER.  Make
sure you are putting userid in VMCPUSER and not VMCPUSE.

Steve,
Before loading the wait PSW(and before or after authorizin VMCF),
set bit 31 of Control Regizter 0 to a value of 1.This setting is necessary
for receiving VMCF(Code X'4001') external interruptions.
