 NAME       : HCPFSATE
 DESCRIPTION: FIXED STORAGE ASSIGNMENT TABLE ENTRY
 DSECT      : FSATE
 FUNCTION   : The FSATE describes fixed storage
              in the V=F Area assigned to a single user.
 LOCATED BY :
        HCPWRKFA  ANCHOR FOR FIXED STORAGE ASSIGNMENT TABLE
        RSASA1ST  FIELD OF HCPRSAMP CONTAINS OFFSET
                  TO AN FSATE WITH THE LOWEST MAIN
                  STORAGE ORIGIN
        RSASALST  FIELD OF HCPRSAMP CONTAINS OFFSET
                  TO AN FSATE WITH THE HIGHEST MAIN
                  STORAGE ORIGIN
        FSAFOFF   FIELD OF HCPFSATE CONTAINS OFFSET
                  TO AN FSATE WITH THE NEXT HIGHER MAIN
                  STORAGE ORIGIN
        FSABOFF   FIELD OF HCPFSATE CONTAINS OFFSET
                  TO AN FSATE WITH THE NEXT LOWER MAIN
                  STORAGE ORIGIN
 CREATED BY :
              THE FIXED STORAGE ASSIGNMENT TABLE IS PERMANENTLY
              ALLOCATED AS PART OF THE RESIDENT NUCLEUS.  IT
              IS LOCATED IN THE HCPWRK MODULE AND IS NOT REFRESHED
              ACROSS A SOFTWARE RE-IPL.
 DELETED BY : NONE
 RELOCATION CONSIDERATIONS : None
 NOTES      : The table contains entries which depict how the V=F area
              is divided and assigned to V=F users.

THE FSAIDXSH EQUATE IS USED TO FORM FSATE OFFSETS BY SHIFTING ZONE NUMBERS. THIS WAY OF FORMING FSATE OFFSETS DEPENDS ON THE SIZE OF THE FSATE BLOCK BEING A POWER OF 2. IF THIS CONTROL BLOCK SIZE SHOULD CHANGE, THE FSAIDXSH MUST ALSO CHANGE, SO LONG AS THE NEW SIZE IS A POWER OF 2. IF NOT, ALL USES OF FSAIDXSH MUST BE CHANGED TO FORM FSATE OFFSETS BY MULTIPLYING ZONE NUMBER BY THE FSATE CONTROL BLOCK LENGTH.
