Hi Stephen,

Comment removal is usually done as part of lexing, so during lexing you will have access to the true source position - if you care about line numbering (and have a split between lexing and parsing) usually you would annotate lexemes with their source position.
Thanks! And sorry for late reply. The answer for me means that I should use common method of separate lexem / parser instead of using parsec with Char Parser. I will do that anyway since it will probably improve the performance of the parser. One more question: Do you know If there is a lexing technology which can inter work with Parsec based Parser ? With inter work I mean that line number information is preserved across lexing/parsing. Rado
