Flags
Precautions Do not program another instruction between CMP(020) and an input condition
that accesses the result of CMP(020) because the other instruction might
change the status of the Arithmetic Flags.
3-6-4 DOUBLE COMPARE: CMPL(060)
Purpose Compares two double unsigned binary values (constants and/or the contents
of specified words) and outputs the result to the Arithmetic Flags in the Auxil-
iary Area.
