Written in a lot of languages so far, in most of them with projects/systems of my own (as in not just adding fixes or functionality to an existing work). But probably not being able to produce (no google/manual peeking) a complex program with many of the ones im not currently programming. Should be more than 15 years that i touched anything on pascal or rexx and also a lot have lookalike structures where i could mix a particular syntax of one into another.
