The CDF_VARGET procedure reads multiple values from a Common Data Format file variable. By default, all elements of a record are read. If INTERVAL, and/or OFFSET are specified but no COUNT is specified, CDF_VARGET attempts to get as many elements of each record as possible.
A vector specifying the array indices within the specified record(s) at which to begin writing. OFFSET is a 1-dimensional array containing one element per CDF dimension. The default value is zero for each dimension.
Set this keyword to return CDF_CHAR and CDF_UCHAR data from the CDF file into Value as string data rather than byte data. This keyword is ignored if the data in the CDF file is not of type CDF_CHAR or CDF_UCHAR.
This warning message indicates that the data was stored in the CDF file with type CDF_CHAR (signed 1-byte characters), but was retreived by IDL with type BYTE (unsigned byte). To turn this warning message off, set !QUIET=1.
