Previous: NDF_STYPE - Set a new type for an NDF array component
- Description:
The routine returns an NDF placeholder which may be used to
create a temporary NDF (i.e. one which will be deleted
automatically once the last identifier associated with it is
annulled). The placeholder returned by this routine may be passed
to other routines (e.g. NDF_NEW or NDF_COPY) to produce a
temporary NDF in the same way as a new permanent NDF would be
created.
- Invocation:
CALL NDF_TEMP( PLACE, STATUS )
- Arguments:
-
PLACE = INTEGER (Returned)
-
Placeholder for a temporary NDF.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
-
Placeholders are intended only for local use within an
application and only a limited number of them are available
simultaneously. They are always annulled as soon as they are
passed to another routine to create a new NDF, where they are
effectively exchanged for an NDF identifier.
-
If this routine is called with STATUS set, then a value of
NDF__NOPL will be returned for the PLACE argument, although no
further processing will occur. The same value will also be
returned if the routine should fail for any reason. The NDF__NOPL
constant is defined in the include file NDF_PAR.
