 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.
