In 1969, I remember getting my first pair of glasses as a third grader. I also vividly remember thinking that I could not imagine being an adult or how much the world would change in the next 50 years. I was young and I had my whole life ahead of me. Now 50 years later, it feels like those years flew by in a flash.
In 1969, something even more significant than my first pair of glasses happened: CICS was released to the world. IBM had started the development of CICS in 1966 in Des Plaines, Illinois, in order to address requirements for the Public Utilities Sector. In 1968, CICS was released to the world as, not surprisingly, PU-CICS. Soon it became evident that the system was applicable to other industries, so they dropped the Public Utilities prefix and the first release of CICS occured in 1969. Development moved to Palo Alto and if it wasn’t for customer pressure to keep it alive, it may have succumbed to its counterpart IMS, which IBM considered more valuable. In 1974, CICS almost had a similar fate when IBM decided to end CICS development to concentrate on IMS. Again, the customers spoke and development was moved to the Hursley Labs in England which had just finished the PL/1 compiler.
CICS Fun Facts:
As CICS has continued to prosper, many new features and functions have been added. In December of 2018, IBM released version 5.5 of CICS/TS for z/OS. I think it is safe to say that CICS is here to stay.
Happy Birthday CICS! You don’t look a day over 29.
