About the construction
| DC AL1(64) A byte containing the number 64
I am even less enthusiastic; z/Architecture now supports loading and
storing single-byte signed binary integers in the same way that it
supports halfword ones, and "containing the number 64" is thus at best
ambiguous. Moreover, I have never really liked using AL1 or an LA
instruction to obtain small unsigned binary constants, although like
everyone else I have resorted to them on occasion. The assembler's
BYTE bif is much more flexible. I can write
lus_64 seta BYTE(x'40') --signed single-byte +64
|&minus_64 seta BYTE(x'd0') --signed single-byte -64
And I see this as impetus to coerce HLASM itself to perform the conversion so as
to make the value match the comment.
