[antlr-interest] Parsing length-prefixed strings...

[Douglas Mayle]

I was hoping someone here might be able to point me in the right
direction.  I've read most of the FAQ, and the document, and I still
haven't got an idea where to head.  In the language I'm parsing a have a
a token stream that includes integers and characters.  However, my
string literals, rather than being bounded on both sides, have an
opening character, a two digit length, and then that many characters.  I
can't figure out how to match this fixed length stream with a parser.  A
string might look like:

;05Hello

or:

;06World!

So I might have

print;05Helloprint;06World!

Now, this isn't the actual language, but the principal is the same, I
can't capture the string with the lexer, and I know I have to do it with
the parser, but I'm not sure how...
