Using library routine retention

If you are going to use library routine retention, you need to be aware of the following:

Library routine retention cannot be used on CICS®.
To successfully initialize library routine retention or terminate library routine retention, Language Environment must not be currently initialized.
For example, if you use CEELRR with ACTION=INIT in a Language Environment-conforming assembler program, library routine retention is not initialized, because the invocation of the assembler program caused Language Environment to be initialized.
