Rational Developer for System z
Enterprise COBOL for z/OS, Version 4.1, Compiler and Runtime Migration Guide


Running in a reusable runtime environment

This section applies to the following compiler options:
Language Environment continues to provide compatibility support for pre-Language Environment methods for managing a reusable runtime environment. Three of these methods include:
When you use the reusable environment with existing applications under Language Environment, the following restrictions apply:

Using STOP RUN will end the reusable environment regardless of the method used to initialize it. If IGZERRE or ILBOSTP0 is called by an assembler program, control is returned to the caller of the assembler program. If you use the Language Environment RTEREUS runtime option, control is returned to the caller of the routine that invoked the first COBOL program.

You can improve the performance when using the COBOL reusable environment or you can allow nested enclaves when running in a reusable environment by modifying the IGZERREO CSECT. For additional information, see the Language Environment for z/OS Customization.
