Block transfer instructions with count

These instructions terminate normally when the word count is exhausted. The PSW and updated NTA are not stored anywhere on normal termination.

If the block transfer terminates because of an SS!=0 response, the PSW and updated NTA will be stored in DM 0 and DM 4. The address contained in DM 4 points to the location where the data would have been stored had SS=0.
