function
| Library: JIS (OMFFJIS) Import : omffjis.xmd | Returns: a scannable input source for streaming data | 
export external string source function reader from value string source input-data
 Use jis.reader to read its value string source input-data argument, and return
      that data converted from a JIS encoding to a UTF-8 encoding. That is, the provided source is in JIS, but the
      program sees UTF-8.
      
 The following program uses jis.reader to convert #main-input from UTF-8 to JIS, and send the
      result to find rules for further processing.
        
import "omffjis.xmd" prefixed by jis. process using group "process input" submit jis.reader from #main-input group "process input" ; ...
 To use jis.reader, you must import OMFFJIS into your program using an import
      declaration such as:
        
import "omffjis.xmd" prefixed by jis.
