It's deliberate, in order to accommodate using legacy assembler
text instream and preserving its existing double ampersands.
I asked the question here and got that answer. If it's not
documented it's surely RCF-worthy.
I played with it a lot. I don't recall what worked. Perhaps:
SET AMP='&&'
...
&.SYSNAME = &SYSNAME
Also, the conventions for preserving column alignment may
be well-motivated but they're inconsistent with the behavior
of symbol substitution elsewhere in JCL.
Also, note that when using PARMDD there's no way to supply
a parameter ending in a blank.
