The routine obtains the value of the specified axis character component of an NDF (i.e. the value of the LABEL or UNITS component for an NDF axis).

CALL NDF_ACGET( INDF, COMP, IAXIS, VALUE, STATUS )

INDF = INTEGER (Given)

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

IAXIS = INTEGER (Given)

VALUE = CHARACTER $\ast$ ( $\ast$ ) (Given and Returned)

STATUS = INTEGER (Given and Returned)

• If the requested axis component is in an undefined state and VALUE is set to a blank string on entry, then an appropriate default value will be returned. If VALUE is not blank on entry, then it will be returned unchanged.

• If the length of the VALUE argument is too short to accommodate the returned result without losing significant (non-blank) trailing characters, then this will be indicated by an appended ellipsis, i.e. ’...’. No error will result.
