Re: concatenating string into $$

[Valter G. Nogueira Jr.]

Tom,

I believe you should not try concatenating "statements".

A better aproach is build a statement tree and then translate it to the
target language.

At least it is what I have seen people doing.

A good source for reference is gcc java's parser.h.
