We receive a JSON message containing an element which is larger than the system long string size. We are using Ensemble HealthShare v2017 which prevents us from using the %GET method as it doesn’t allow us to define the output as a Stream. We are instead trying to the read the contents of the JSON message using Readline function, and store the value into an instance of the %Stream.GlobalCharachter class, and then read from the instance of that class and write the contents of that element into a HL7 Message.
