In open code, people often coded
LABEL EQU *
but, if there was an odd-length constant prior to it, it
would not be halfword aligned, so people started using
the DS 0H technique, instead. (Also, IIRC, the TEST
instruction has more information if you code as DS 0H.)
Of course, with modern HLASM it's preferable to code 'DC
0H' rather than the 'DS 0H' as required by older assembler
implementations.
Would you please elucidate? IIRC, DS 0H will fill
with zeros just as will DC 0H. Why is the latter preferable?
