Business Value Discussion
v CICS Transaction Server for VSE/ESA REXX is useable by business people
Quite often, business people who best understand the business and their required solutions have ideas
on modifying or enhancing the applications they use. However, without extensive training and
experience with a programming language, they may be unable to implement the ideas. One of the
greatest strengths of REXX is its simplicity and "naturalness" on the one hand, and its powerful
capabilities on the other. CICS Transaction Server for VSE/ESA REXX makes it possible, in some
cases, for CICS application users to customize and even extend applications without expending scarce
programmer resources. This allows more effective tailoring of applications to individual business needs.
CICS Transaction Server for VSE/ESA REXX facilitates the use of a prototyping methodology. The
users of an application under development can participate very closely in the application development
process. The end result is that those who have the best understanding of the business and their own
needs can better ensure that the application solution delivered matches their needs. This close
involvement has the added benefit of addressing human factor needs (useability) earlier in the
application development cycle.
v CICS Transaction Server for VSE/ESA REXX facilitates systems management
One of the major uses of REXX is as a Procedures (Scripting) Language. CICS Transaction Server for
VSE/ESA REXX can be used to automate sequences of CICS system and application systems
management activities, providing greater productivity and reliability.
Since CICS Transaction Server for VSE/ESA REXX supports application development (and testing)
directly under CICS, systems management can be simplified.
