NDF_CINP - Obtain an NDF character component value via the ADAM parameter system

Description:

The routine obtains a new value for a character component of an NDF via the ADAM parameter system and uses it to replace any pre-existing value of that component in the NDF.

Invocation:

CALL NDF_CINP( PARAM, INDF, COMP, STATUS )

Arguments:

PARAM = CHARACTER $*$ ( $*$ ) (Given)

Name of the ADAM parameter.

INDF = INTEGER (Given)

NDF identifier.

COMP = CHARACTER $*$ ( $*$ ) (Given)

Name of the character component for which a value is to be obtained: 'LABEL', 'TITLE' or 'UNITS'.

STATUS = INTEGER (Given and Returned)

The global status.

Notes:

• A "null" parameter value is interpreted as indicating that no new value should be set for the character component. In this event, the routine will return without action (and without setting a STATUS value). A suitable default value for the character component should therefore be established before this routine is called.
