     NAME       : HCPFCSPL
     DESCRIPTION: FCP List Directed IPL Parameter List
     DSECT      : FCSPL
     FUNCTION   : Define references for parameter list data
                  returned by the parser after processing the SET
                  and QUERY LOADDEV commands.  This is a
                  temporary storage area that is created and
                  destroyed each time a command is processed.
