Adding Enterprise COBOL programs to existing COBOL applications

When you add an Enterprise COBOL program to an existing application, you are either recompiling an existing program with Enterprise COBOL or including a newly written Enterprise COBOL program. When you add Enterprise COBOL programs to your existing applications, you have the ability to:

Restriction: On CICS, you cannot mix OS/VS COBOL programs and Enterprise COBOL programs in the same run unit. (EXEC CICS LINK and EXEC CICS XCTL will create a separate run unit.)

Important

After you add an Enterprise COBOL program to an existing application, that application must run under Language Environment.

This chapter includes information on the following topics:
When you begin adding Enterprise COBOL programs to your existing applications, you need to know the implications of link-editing existing applications with Language Environment. First, you must use the SCEELKED link-edit library, which impacts the remaining programs in the applications. How it affects existing applications depends on whether the application is comprised of:
