Accumulator Instructions 14.11 +AR1 Add ACCU 1 to Address Register 1 Format Description Status word Example 1 +AR1 +AR1 Parameter Data Type Description Pointer constant Address added to AR1 +AR1 (add to AR1) adds an offset specified either in the statement or in ACCU 1-L to the contents of AR1. The integer (16 bit) is initially expanded to 24 bits with its correct sign and then added to the least significant 24 bits of AR1 (part of the relative address in AR1). The part of the area ID in AR1 (bits 24, 25, and 26) remains unchanged. The instruction is executed without regard to, and without affecting, the status bits. +AR1: The integer (16 bit) to be added to the contents of AR1 is specified by the value in ACCU 1-L. Values from -32768 to +32767 are permissible. +AR1 : The offset to be added is specified by the address.
