IBM’s CICS software is apparently going strong, even after four decades.
CICS means Customer Information Control System, and is pronounced “kicks.” It’s a mainframe transaction processing application. Massively scalable, massively reliable.
Back in the early 1980s, I worked with CICS on IBM System/370 mainframes, and did some integration programming around it. Haven’t thought about it in years, until reading this story about the anniversary, “IBM Touts CICS Relevance 40 Years On,” published by eWeek Europe.
To be honest, I don’t remember too many details about CICS, but there are still some old manuals in my bookcase. Learn more about CICS on Wikipedia.
