How old is that code? What portable UNIT esoteric is advised for a temp DSN?

I thought, TSO. Silly design.
A mischievous developer might create a command environment named
ADDRESS with an ADDRESS command so:
address ADDRESS 'ADDRESS'
... would work without error.
Contrariwise, when I used CMS/370 ISPF many decades ago, ADDRESS ISREDIT
was mis-implemented. Something like:
address ISREDIT 'MACRO'
"RC(-3)"
... but:
address ISREDIT 'ISREDIT MACRO'
... succeeded.
