In general, Language Environment provides the same ILC support for applications running under CICS® as for those running in a non-CICS environment. If there is any ILC within a run unit under CICS, each compile unit must be compiled with a Language Environment-conforming compiler.

If you are using ILC in CICS DL/I applications, EXEC CICS DLI and CALL xxxTDLI can only be used in programs with the same language as the main program. CEETDLI is not supported on CICS.

XPLINK-compiled functions cannot run under CICS Transaction Server prior to CICS TS 3.1.

Fortran cannot run under CICS.
