Gets the maximum and minimum range for the current HDF Scientific Data Set.

maxvalue—The maximum data value for the HDF Scientific Data Set.

minvalue—The minimum data value for the HDF Scientific Data Set.

status—The status of the function call, where:

Help—If present and nonzero, lists the usage for this routine.

Usage—If present and nonzero, lists the usage for this routine. (Same as the Help keyword.)

The maximum and minimum data values for the current Scientific Data Set are obtained.

The data type of maxvalue and minvalue is determined by the numeric type returned by HDFGETNT.

hdf_init

@hdf_common

status = HDFGETRANGE(max, min)

IF (status EQ FAIL) THEN $

   MESSAGE, 'HDFGETRANGE failed.'
