I don't recommend to use labels and goto statements at all. It just messes the code and tells about bad programming manners.

Gotos have use for automatically generated code, for example the re2c Lexer generator. I made a re2p (prototype), which generates similar pascal code with goto's and it compiles into efficient code with Delpi 2005. Except that generating label definitions is a pain :^(.

I don't know this program, but e.g. flex doesn't generate any gotos, even tough it generates C where gotos are somewhat more common than in Pascal, but instead uses a switch (case) statement. (Actually, the flex output does contain a few gotos, but funnily in the hand-written code which is just copied into the output. So I suppose they could be replaced in this code just as well as in any other code.)
