Re: Re^2: Mission critial code required: I have some code in BASIC and require it to be translated to perl

That is one option. I tend to prefer, after a few times doing this, to rewrite the app. The number of improvements and bugs fixed tend to outweigh the number of errors. Granted, I have only worked with relatively young apps and rewriting them after they were implemented by junior developers. *shrugs* YMMV, as with everything.
