Best approach to create a syntax reader for a code converter?

[Skipper]

..... I had help from Skipper with the tokenizer and I managed to replicate it, but the Parser and lexer analyzer part is the worst xD

Likely I did not help @Skinkairewalker all that much. I just provided a binary of an Eiffel-tokenizer I'm implementing with Purebasic, and some Eiffel source files to play with. The binary shows the token stream and some statistics about the process, nothing more. It's not completely ready yet, so no AST-builder created yet either... For me, this is a learning tool, more than anything else...

Cheers
