a special external interrupt X'4001' unless: There is already a special external interrupt posted. The virtual machine is running disabled for VMCF interrupts (PSi bit 1 and CRO bit 31). Transfers data from one virtual storage to another virtual storage.
Errors occurring during data transfer are reflected to originating
virtual machine via the data transfer return code in the final
response interrupt message header. DMKVMCEX ---Called from DMKDSP to reflect an external interrupt message header to
a virtual machine. If the VMCF subfunction is a SENDX, the SOURCE data is moved into the external interrupt buffer immediately
following the message header. DMKVMCUA ---Called by DMKCFP when a virtual machine is logged off or reset. Uses the VMCUAUTH subroutine (subfunction code X'OOOl') to dispose of
existing VMCBLOKS before turning off virtual machine communication.
