Concord, New Hampshire
Working with IBM mid-range computers (System/34, System/36, System/38, AS400/iSeries/i5) since graduating with a BS in Computer Science in 1981. Been working with the AS400 since the B60 beta program back in 1988.
If it was a language on one of these systems I've probably used it - RPG(II, III, ILE), COBOL, Synon/CoolPlex, OCL, CL, DDS, 36 Assembler, MI code, SQL(embedded and standalone) and Java.
I've also played with the PC since it first came out. C programming from floppies, Windows 3.1 beta, Visual Basic, Delphi, C++. Had some software bundled with the early 5250 emulator cards for Host to PC file transfers. But I always considered this more of a hobby than work.
