The routine assigns the name of an NDF to a message token (in a form which a user will understand) for use in constructing messages with the ERR_ and MSG_ routines (see SUN/104).

CALL NDF_MSG( TOKEN, INDF )

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

INDF = INTEGER (Given)

• This routine has no STATUS argument and performs no error checking. If it should fail, then no assignment to the message token will be made and this will be apparent in the final message.
