RCUNC-Release Core Block and Unhold File Record

This general macro combines the functions of the RELCC and UNFRC macros. It releases the storage block referenced by the specified core block reference word (CBRW) from the entry control block (ECB) and returns it to the appropriate available storage pool. Then it releases the hold on the file record address referred to by the corresponding file address reference word (FARW).

The CBRW is made available for use, and the FARW is unchanged. If another entry has a request pending to find and hold the file record concerned, it is activated by this macro.
