JSON-CODE Exception Codes

Your COBOL system supports the following exception codes that are available via the JSON-CODE special register. If one of these exceptions occurs, control is passed to the statement in the ON EXCEPTION phrase, or to the end of the JSON GENERATE statement if you did not code an ON EXCEPTION.

Code Description
1 The receiver was too small to contain the generated JSON text. The COUNT IN data item, if specified, contains the count of character positions that were actually generated.
