Gets the address of the routine that processes
the CP console function that was requested.
Processes a CP console function.
Processes the SLEEP command.
Processes the BEGIN command.
Processes the QUERY command. Presents an attention interruption to the virtual
machine to simulate a real request key
interruption.
Pageable.
Processes LOCATE and ADSTOP commands. Stops virtual machine at specified address (ADSTOP command).
Displays address of real device blocks, or VMBLOK and/or virtual device blocks (LOCATE command).
Pageable.
Handles Diagnose code X'64'. Entry to IPL from LOGON (DMKLOG). Entry to IPL from a command line (DMKCFM). Pageable. Saves a virtual machine's storage space including
registers and PSi (SAVED System). Resident.
