stream

A CHARACTER expression that specifies the name of a stream to which the AVM writes the JSON string. If you specify the empty string (""), the AVM writes the JSON String to the default output stream. For WebSpeed, write the JSON string to the WebSpeed-defined output stream (WEBSTREAM).

For more information about using ABL unnamed output streams, see the DEFINE STREAM statement reference entry and the chapter on alternate I/O sources in OpenEdge Development: Programming Interfaces. For more information about using WebSeed-defined output streams, see OpenEdge Application Server: Developing WebSpeed Applications.

formatted

A CHARACTER expression that specifies the name of a stream to which the AVM writes the JSON string. If you specify the empty string (""), the AVM writes the JSON string to the default unnamed output stream. For WebSpeed, write the JSON string to the WebSpeed-defined output stream (WEBSTREAM).

encoding

An optional string indicating the Unicode Transformation Format of the JSON string to be written. Valid values for UTF are "UTF-8", "UTF-16", "UTF-16BE", "UTF-16LE", "UTF-32", "UTF-32BE", and "UTF-32LE". If the value is the empty string (""), the Unknown value (?), or not given, the parameter defaults to "UTF-8".
