DRL ADDMEM (octal 16) - add memory.

Usage:

drl addmem

Where:

c(a): Contains a return address in the upper half, and zero in the lower.
c(q): Contains zero in the upper half of the word and the number of words of memory desired in the lower half.

Description:

This derail is the same as RELMEM except that the value in Q is interpreted as a request for additional memory at the upper boundary. A subsystem may not obtain memory at the lower boundary, and the number of words must be modulo 1024.
