CEEBSHL — exit from/re-entry to Language Environment shell

CEEBSHL is a CWI routine, which is called just before exit from, and just after re-entry to, Language Environment. This allows the Language Environment to be appropriately altered to accommodate the switch in states from a dormant environment to an active environment and vice versa.
