CICS support

If you do not specify the PP(CICS) option, EXEC CICS statements are parsed and variable references in them are validated. If they are correct, no messages are issued as long as the NOCOMPILE option is in effect. Without invoking the CICS preprocessor, real code cannot be generated.

You can use EXEC CICS statements in PL/I applications that run as transactions under CICS.

You can develop these applications under CICS on Windows for eventual execution under CICS that particular development platform or under CICS/ESA, CICS/MVS, or CICS/VSE systems on S/390.

Make sure that the CICS installation adds all the \OPT\... settings to your system environment variables for Windows support. It is not necessary that the CICS system be operational when you are compiling your programs.
