Description:
The routine creates a new primitive NDF and
returns an identifier for it. The NDF may subsequently be manipulated with the NDF_ routines.
Invocation
CALL NDF_NEWP( FTYPE, NDIM, UBND, PLACE, INDF, STATUS )
Arguments
FTYPE = CHARACTER
∗ (
∗ )
(Given)
Data type of the NDF’
s DATA component (e.g. ’
_REAL’
). Note that complex types are not
permitted when creating a primitive NDF.
NDIM = INTEGER (Given)
Number of NDF dimensions.
UBND( NDIM ) = INTEGER (Given)
Upper pixel-index bounds of the NDF (the lower bound of
each dimension is taken to be 1).
PLACE = INTEGER (Given and Returned)
An NDF placeholder
(e.g. generated by the
NDF_PLACE routine) which indicates the position in the data system where the
new NDF will reside. The placeholder is annulled by this routine, and a value of NDF__NOPL will be
returned (as defined in the include file NDF_PAR).
INDF = INTEGER (Returned)
Identifier for the
new NDF.
STATUS = INTEGER (Given and Returned)
The global status.
Notes:
-
This routine creates a "
primitive"
NDF, i.e. one whose array components are stored in "
primitive"
form by default (see SGP/38).
-
The full type of the DATA component is specified via the FTYPE argument and the type of the
VARIANCE component defaults to the same value. These types may be set individually with the
NDF_STYPE routine if required.
-
If this routine is called with STATUS set, then a value of NDF__NOID will be returned
for the INDF argument, although no further processing will occur. The same value will
also be returned if the routine should fail for any reason. In either event, the placeholder
will still be annulled. The NDF__NOID constant is defined in the include file NDF_PAR.
