Load input word IW36 into ACCU 1.
Load a constant into ACCU 1. The previous contents of ACCU 1 are shifted

Transfer the result (contents of ACCU 1) to input word IW36.

Set the 8 low-order bits in input word
IW36 to “1”. Compare both words

If either of the corresponding bits is
“1”, a “1” is set in the result word.
