     FUNCTION   : CONTAINS THE NAMES AND POINTERS TO ALL CREATED
                  CFLF CONFIGURATIONS.
     LOCATED BY : SYSCMCFN IN HCPSYSCM.
     CREATED BY : HCPLFCST
     DELETED BY : HCPLFCST, HCPLFCRL
     SERIALIZED : CFLF CONFIGURATION LOCK.
     Notes      : The maximum configurations are 250.  This allows the
                  use of HCPGETST and free storage subpools.  If the max
                  is increased beyond 252 then the HCPGETST with the
                  PAGES=DECIDE option will have to be used since the there
                  would not be room for the data and free storage header
                  and trailer in one page.
