In that era, did '&&TEMP' represent a temporary data set, or was it a
later accommodation to avoid errors resulting from unintended substitution?
Kolusu's citation quotes Ed J. as:
IBM does not mention the single ampersand being valid temporary
data set name syntax ...
They do now, according to Kolusu's more recent citation.
Still, I believe IBM is making it needlessly complex. I believe:
If the result of symbol substitution is a single ampersand
followed by a single qualifier it represents a temporary
data set name.
Can anyone supply a refutation of this simple rule?
