NDF_ACGET - Obtain the value of an NDF axis character component

Description:
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).

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

Arguments:
INDF = INTEGER (Given)
NDF identifier.
COMP = CHARACTER * ( * ) (Given)
Name of the axis character component whose value is required: 'LABEL' or 'UNITS'.
IAXIS = INTEGER (Given)
Number of the axis for which a value is required.
VALUE = CHARACTER * ( * ) (Given and Returned)
The component's value.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • 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.
