These are a few languages that I am not familiar with but would like to learn more of someday:
PowerBasic, COBOL, PowerBuilder, Delphi

Use at your own risk.  Be sure to compensate the authors if you find any of this software useful.

PowerBASIC 

A small, but powerful easy to use language. Was good for back-end processing that does have to look pretty.

Here I offer you a trial version of Power Basic Lite.  It does not appear to be crippled at all. It is the kind of language that you could pick up on your own, if so inclined. It is from 1991, buyer beware!

Want some COBOL? 

I have read that the majority of code running throughout the world today is still written in COBOL.  Yet it does not get a lot of recognition these days.

Well below is a COBOL info link and to the right are a few shareware COBOL downloads that I have accumulated over the years.
