That was me. It was in response to Nancy's question about indirection.

The form of indirection you are trying is not standard nor is it supported by GT.M.

Try putting the "$$" inside the quotes.
I don't think this is standard either (or documented in GT.M for that matter), but this works for me.
s test="$$ucase^%zString" w @test@("hello kevin")
HELLO KEVIN
