1. json is a level 01 data item for which the IS IDENTIFIED clause has been used.
2. hasDummyRoot is an alphanumeric data item or literal hosting a boolean value (e.g. "0", "1", "true", "false", "yes", "no", "on" or "off"). If the boolean value is TRUE, then the top level item of Record-Definition is discarded and will not appear in the JSON stream . This parameter can be NULL, in such case, FALSE is assumed.
3. encoding is a string literal or data item that specifies the character set to be used in the JSON stream. All the canonical names listed in the following Java documentation can be used as value for this property: http://java.sun.com/javase/6/docs/technotes/guides/intl/encoding.doc.html.
General Rules
1. The MIME type “application/json” is automatically applied.
2. The stream is returned when the program terminates (e.g. upon EXIT PROGRAM or GOBACK statements).
