Writing a CEEBINT initialization exit for Language Environment

All programs running under Language Environment® invoke a subroutine called CEEBINT at program initialization time, just after invocation of the CEEBXITA and CEECSTX exits. The runtime environment is fully operational at this point and Language Environment calls this program the HLL user exit. Language Environment provides a module containing this program in the SCEELKED library (it simply returns to its caller) and this is, therefore, the installation default version. However, you can also write and link-edit a tailored version in to any program to replace the default.

Ordinary Language Environment coding rules apply to CEEBINT, and you can write it in C, C++, PL/I, or Language Environment-conforming assembler. CEEBINT applies to COBOL programs just as any others, but it cannot be written in COBOL or call COBOL programs. If CEEBINT introduces a second HLL to a program, the rules for mixing HLLs described in Mixing languages in Language Environment apply.

For more information on the High Level Language user exit, CEEBINT, see the z/OS Language Environment Programming Guide.
