Know what you mean. I modified a program which always moved 2 bytes from
a buffer to a HALFWORD DS H before doing an LH on HALFWORD. Likewise, it
always did an STH to HALFWORD, then moved to the buffer. The buffer did
not have any guaranteed alignment. Since it was, and still is, a highly
used subr
I would like to use LB for signed bytes and LLC for unsigned. LB does
sign extension and LLC clears the other bytes to zeros. But I can't
remember if our z9BC supports them.
