* THE FUNCTION OF DMSOR1 IS TO RELOCATE ALL DTF TABLE * 00009000
* ADDRESS CONSTANTS FROM THE ASSEMBLED ADDRESSES TO * 00010000
* EXECUTABLE STORAGE ADDRESSES. THIS IS ACCOMPLISHED BY * 00011000
* SUBTRACTING FROM THE BAL ADDRESS PROVIDED BY THE * 00012000
* OPENR MACRO IN REGISTER 0 A FOUR BYTE ASSEMBLED * 00013000
