I have problems using the delphi version of lex

the problem is: it seems there is no yylex() function
like in the C version of lex. instead there is the
following declaration in the file created by dlex:

function TLexer.parse() : integer;

but this function is simply not implemented and there
exists no TLexer class... so I wonder how to compile
the dlex created file in delphi.

I have also another problem with dlex - in the C version
it is possible to define start states, i.e. %start COMMENT
this works also in dlex, but when I try to write rules for
a specific state with <COMMENT>rule I alays get the error:
202: undefined symbol.

is there anyone here who successfully used dlex?
I'm looking for sample code since a week now and could
not find anything :(

Thank you for your help.
