address value expression
is ambiguous in BNF. It can mean either:
Issue the command "expression" in the environment named "value"
or:
make the value of "expression" the new environment name.
However, REXX customarily applies "common sense" rules,
and makes VALUE a keyword.
If I had been emperor of the REXX Universe, I would have
provided only two forms:
ADDRESS symbol [command]
and
ADDRESS ( expression ) [command]
