DFSRHSH0

DFHRHSH0 is called to reduce the resource name used to request a global lock to a fourteen-bit binary value. The resource name to be hashed is contained in the eight bytes beginning at PSTRSRNA in the PST. The hash value is returned to the caller in the four bytes at PSTRSHSH.

DFSRHSH0 consists of two routines, each one having its own entry point. The routine at entry point DFSRHSH1 hashes an RNA (resource name) which contains and RBA. The routine at entry point DFHRHSH2 hashes an RNA containing an RBN.
