USXBK Prolog

 NAME       : HCPUSXBK
 DESCRIPTION: User Security Extension Block
 DSECT      : USXBK
 FUNCTION   : The USXBK contains pointers to the block(s)
              of storage containing the altered security flags for
              a particular user, or zeroes, if no block exists for
              that set of entities.
 LOCATED BY : VMDACIMP field of the VMDBK
 CREATED BY : HCPDA0
 DELETED BY : HCPDA0, HCPUSO, HCPLOG
 SERIALIZED : The SYSCM lock, SYSUSXLK
 RELOCATION CONSIDERATIONS : None
 NOTES      : This control block is bilingual.  The fields within it can
              be referenced in either ASSEMBLER or PLAS modules.
              The block of storage pointed to by each pointer field
              in the USXBK consists of as many bytes as there are entries
              in its corresponding data area.  For example, USXCP
              would point to a block of storage containing as many
              bytes as there are command table entries.  These
              bytes have a one to one correspondence with the entries
              in the command table.  IE the 5th byte contains the
              extended security flags relative to the 5th command
              defined within the command table.
