ALTER MAP AND SELECT PHYSICAL SEG1ENI' allows an operation to alter the
physical segment with that address subrange map entry. This physical mode operator is the equivalent of the logical mode operator AIlIER MAP AND SELECI' DA'm SEG1ENI'. One difference is that the mapping facility area is not updated by this operator. Another difference is that map entry 4 can be updated by this operator. The first operand is a double byte specifying which map entry/data segment, segment descriptor register. is to be altered. The second operand is a double byte containing new entry state information. The third operand is a double byte containing the starting address of the new subrange to be mapped. The fourth operand is a double byte containing the mask used to spec ify size of the new subrange. The fifth and sixth operands are a word (32 bits) containing the
