After you add Language Environment to the LNKLST/LPALST, Language Environment is available to all of your applications. To ensure that all applications are functioning correctly under Language Environment before adding Language Environment to your LNKLST/LPALST, you can temporarily install Language Environment in LNKLST/LPALST or use STEPLIB.
Do not make more than one COBOL runtime library available to your applications at execution time. For example, there should be one and only one COBOL runtime library, such as SCEERUN for Language Environment, in LNKLST. If you have more than one, you will either get hard-to-find errors or you will have an unused load library in your concatenation. When you add Language Environment to LNKLST/LPALST, remove any other COBOL runtime libraries, such as COBLIB, VSCLLIB, and COB2LIB.
