Explanation
• During block operations, turning SM705 ON makes it possible to use the
mask pattern being stored at SD705 (or at SD705 and SD706 if double
words are being used) to operate on all data in the block with the
masked values.
• Patterns masked by use of the IMASK instruction are stored in the
following manner:
b15
SD715 l15 to
l31
SD716 to
SD717 l47 to
• For use as replacement for accumulators used in A series programs.
Stores the program number of the program to be loaded by the PLOADP
instruction when designated.
Designation range: 1 to 124
• Stores the message designated by the MSG instruction.
