     NAME       : HCPASMBK
     DESCRIPTION: PTRM Address Space Management Block
     DSECT      : ASMBK
     FUNCTION   : Manage the i-ASITs corresponding to the ASCBKs

     LOCATED BY : RSAASITB - Field in HCPRSAMP
     CREATED BY : HCPPRM - At system initialization time
     DELETED BY : none
     SERIALIZED : RSAPRLK - PTRM address space resolution lock
     COMMENTS   : none
