Function

      DMSDMP IS THE SIMULATED $$BDUMP/$$BPDUMP ROUTINE       *
      UNDER CMS/DOS.  DMSDMP IS ENTERED WHENEVER A DUMP OR   *
      JDUMP MACRO IS ISSUED. DMSPDP IS AN ENTRY POINT FOR    *
      PDUMP REQUESTS.  IN BOTH CASES, A 'CP DUMP' COMMAND    *
      IS ISSUED DIRECTING THE DUMP TO AN OFFLINE PRINTER.    *
                                                             *

Attributes

Operation

     DMSDMP PERFORMS THE CP CONSOLE FUNCTION 'DUMP'  AND    *
     DUMPS FROM LOCATION 0 TO THE TOP OF VIRTUAL STORAGE.   *
     DMSDMP EXITS WITH AN SVC 6 (CANCEL).                   *
                                                            *
     DMSPDP FIRST VERIFIES THAT ADD1 AND ADD2 DO NOT VIOLATE*
     ANY OF THE RULES FOR ADDRESSES AS OUTLINED ABOVE UNDER *
     ERROR MESSAGES.  IF ADD2 > EOCADR IN BGCOM, ONLY       *
     STORAGE UP TO EOCADR IS DUMPED.  PDUMP IS ACCOMPLISHED *
     VIA DIAGNOSE (CODE 8).  PROCESSING CONTINUES AFTER     *
     THE DUMP OPERATION  EXIT IS MADE FROM DMSPDP VIA       *
     SVC 11.                                                *
                                                            *
                                                            *
