(Word 4) COMMREQ Status Word Pointer Offset:
This word contains the offset within
the memory type selected. The status word pointer offset is a zero-based number. For ex-
ample, if you want %R1 as the location of the CRS word, you must specify a zero for the
offset. The offset for %R100 would be 99. Note, however, that this is the only zero-
based field in the Channel commands.
