After your system has been designed, the programming effort to turn the specification into a working application is normally divided between two groups: the people who install and maintain the system and those who write the application programs it will use. (We don't want to rule out the possibility of all this work being done by one heroic person.) CICS offers a variety of helpful features for both groups. Concentrating on the application programming side, CICS aids include:
A choice of programming language. You can write your application programs in assembler, COBOL, PL/I, or C language.
A command-level programming interface with CICS. You need know little about how CICS works. You request data or communication with terminals by issuing CICS commands that resemble those of the programming language you are using. A command language translator preprocesses the application source code, translating CICS commands into CALL statements in the language of the application program. It also provides useful diagnostics.
An execution diagnostic facility (EDF), for testing command-level application programs interactively.
