The IBM CICS computing environment is one of the largest concentrations of customer production applications and data in the world. There has been tremendous customer investment in CICS-based mainframe systems, CICS-based application development, data collection for CICS-based systems, and employee education relating to the use and support of CICS-based systems. CICS Transaction Server for VSE/ESA REXX helps preserve and enhance the usefulness of this investment.
Not only does CICS Transaction Server for VSE/ESA REXX enhances the delivery of traditional CICS-based production applications, it makes the CICS environment suitable for a broader range of information processing activities. With CICS Transaction Server for VSE/ESA REXX, it is now practical to also perform end-user computing, prototyping, and application development directly within the CICS environment, either in separate or common regions.
