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

CALL NDF_AFORM( INDF, COMP, IAXIS, FORM, STATUS )

INDF = INTEGER (Given)

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

IAXIS = INTEGER (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 axis array. This constant is defined in the include file NDF_PAR.

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