DMSOR3 *
*
Function
THE FUNCTION OF DMSOR3 IS TO RELOCATE ALL DTF TABLE *
ADDRESS CONSTANTS FROM THE ASSEMBLED ADDRESSES TO *
EXECUTABLE STORAGE ADDRESSES. THIS IS ACCOMPLISHED BY *
SUBTRACTING FROM THE BAL ADDRESS PROVIDED BY THE *
OPENR MACRO IN REGISTER 0 A FOUR BYTE ASSEMBLED *
ADDRESS CONSTANT OF THE BAL ADDRESS. ANY DIFFERENCE *
INDICATES THAT THE PROGRAM HAS BEEN RELOCATED. *
RELOCATION IS PERFORMED FOR UNIT RECORD DTFS. *

Operation
DMSOR3 PERFORMS THE FOLLOWING FUNCTIONS: *
1. DETERMINES IF RELOCATION IS RE- *
QUIRED. IF NOT EXIT IS MADE TO *
$$BOPEN TO OPEN THE FILE. *
*
2. DETERMINES WHAT DTF TYPE IS THE *
OBJECT OF THE OPENR MACRO. *
*
MODIFIES THE ADCONS IN THE *
UNIT RECORD DTFS. *
*
3. AN SVC 2 (FETCH) FOR DMSOR2 IS *
ISSUED FOR DTFCP OR DTFDI DTFS. *
*
3. A CHECK IS MADE TO SEE IF MORE *
FILES REMAIN TO BE OPENED. IF *
SO, ADDRESS MODIFICATION IS PER-*
FORMED ON THOSE DTFS AND THEN AN*
SVC 2 IS ISSUED TO FETCH $$BOPEN*
Calls to Other Routines
DMSBOP (SVC 2) *
DMSOR2 (SVC 2) TO MODIFY DTFCP/DTFDI ADCONS *
