Biographical Sketch: I am a professor of Computer Science at The TSYS School of Computer Science at Columbus State University in Georgia. I have been using IBM Assembly language since the late 70's. Columbus is home to a large credit card transaction processing company and a Fortune 500 insurance firm, and I've had the pleasure of training 1200+ students in Assembly Language both corporately and at CSU. Many are still making a living at it, in spite of me.
