I tried doing:   return "${xx}"
But that returns a string which starts and ends with a quote.
i.e. the quotes become part of the string.

I think it would be safest let the parser map 'return ${xx}' to
'Return(${xx})'.
If somebody wants to do math, they can do it prior to the 'return'
statement as shown in the example posted by Marquis' this morning.

Please note: this issue is not related to the issue I posted at 2010-01-21
21:27.
i.e. there are two unrelated problems which need to be dealt with
separately.
1) Direct assignment of macro to variable gives a syntax error.
2) Arg to 'return' is subject to math evaluation when it should not be.
