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.
