Initializing library routine retention

To use Language Environment library routine retention in an IMS™ dependent region, you must do the following:

In your JCL or procedure used to bring up IMS dependent regions, specify that you want IMS to invoke dependent region preinitialization routines. Do this by specifying a suffix on the PREINIT keyword of the IMS dependent region procedure.
In the DFSINTxx member of IMS.PROCLIB (where xx is a suffix specified by the PREINIT keyword), include the name CEELRRIN or CEELRRXP.

When IMS invokes the module CEELRRIN or CEELRRXP, Language Environment library routine retention is initialized.

Note: The source for module CEELRRIN or CEELRRXP is available in the SCEESAMP library in member CEELRRIN or CEELRRXP. If this source does not meet your needs, you can create your own assembler program to initialize Language Environment library routine retention. If you create your own load module to initialize Language Environment library routine retention, you need to put the name of the module in the DFSINTxx member.
