The routine returns the storage form of an NDF array component as an upper case character string (e.g. ’SIMPLE’).

CALL NDF_FORM( INDF, COMP, FORM, STATUS )

INDF = INTEGER (Given)

COMP = CHARACTER $\ast$ ( $\ast$ ) (Given)

FORM = CHARACTER $\ast$ ( $\ast$ ) (Returned)

STATUS = INTEGER (Given and Returned)

• The symbolic constant NDF__SZFRM may be used for declaring the length of a character variable to hold the storage form of an NDF array component. This constant is defined in the include file NDF_PAR.

• At present, the NDF_ routines only support "primitive", "simple", "delta" and "scaled" arrays, so only the values ’PRIMITIVE’, ’SIMPLE’, ’DELTA’ and ’SCALED’ can be returned.
