Have I missed something, or is the solution to this fairly simple?
1. In library member 'DC':
MACRO
&NAME DC &PARM...
...
MEND
2. In code, to get the DC macro 'in front of' the assembler DC:
COPY DC
3. In the DC macro, use mnemonic tagging to access the assembler DC:
<label> DC:ASM <DC parameters>
If (and only if) mnemonic tagging overrides OPSYN (not clearly defined
in the book, AFAICS), this could be even simpler:
DC OPSYN MYDC
then, within MYDC:
<xxx> DC:ASM <yyy>
Does anyone know if mnemonic tagging overrides OPSYN?
