     NAME       : HCPFSATE
     DESCRIPTION: FIXED STORAGE ASSIGNMENT TABLE ENTRY
     DSECT      : FSATE
     FUNCTION   : THE FSATE DESCRIBES FIXED STORAGE
                  IN THE V=R REGION 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
     NOTES      : THE TABLE CONTAINS ENTRIES WHICH DEPICT HOW THE V=R REGION
                  IS DIVIDED AND ASSIGNED TO V=R AND V=F USERS.

         The following macro invocation is to ensure that no CHANGES ARE MADE TO
         THE SIZE OF THIS CONTROL BLOCK WITHOUT PAYING ATTENTION TO THIS BLOCK
         COMMENT.
         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.
