Sets attribute metadata to be included in the output file created with the sdfwrite command.

varname           May be set to "global", "longitude", "latitude", "level", "time", "ensemble", or
                  a defined variable name
attribute_type       May be one of five data type types (valid aliases in parentheses):
                  "char" (String, Str, Url)
                  "short" (Int16, UInt16)
                  "int" (long, Int32, UInt32)
                  "float" (Float32)
                  "double" (Float64).
attribute_name    May be any single word or string with no spaces (e.g.: "units", "long_name")
attribute_value   May be any string as long as the length of the entire entry does not exceed 512 characters.
                                    For numeric types, may be a list of comma-delimited numerals.

Usage Notes

This command is available in GrADS v2.0.a3 or higher.

The reset command will release all the attributes from memory. To do this without resetting all the other user-specified options, use the clear sdfwrite command.
