Library routine retention and preinitialization

The Language Environment preinitialization services can be used while library routine retention is initialized. However, the Language Environment resources initialized and terminated with Language Environment preinitialization services are not kept in memory when library routine retention is initialized. There is no sharing of resources between Language Environment when initialized with preinitialization services and an environment initialized by invoking an HLL program without using preinitialization services. There is no performance benefit of library routine retention for those applications and subsystems that bring up a Language Environment preinitialized environment, and then use the preinitialization services to invoke programs that require Language Environment.
