The value= keyword must be present to specify the internal integer value to be associated with the classification. The smallest integer that can be specified is 0. The maximum size integer that can be specified is 255. The decimal integer specified for the value starts with the first non-blank character following the blank after the keyword, and continues up to the next semicolon or the end of the line. A null integer specification, as in the specification:
is taken to be 0. If value= is specified more than once for the same classification name, all specifications except the last are ignored. Hence, value= should be specified only once. A particular value should be specified only once in the encodings file.
