I think Brian's confusion here is partially about initQuickstart() adding
an unexpected value in MSH-9-3.
Similar to your suggestion, Ian, I think what Brian might be looking for is
something like this to remove the value afterward:
ORR_O02 o02 = new ORR_O02();
o02.initQuickstart("ORR", "O02", "P");
System.out.println(o02.toString().replaceAll("\r", "\n"));
o02.getMSH().getMessageType().getMessageStructure().setValue(null);
System.out.println(o02.toString().replaceAll("\r", "\n"));
Which produces:
MSH|^~\&|||||20151217123953.819+0100||ORR^O02^ORR_O02|210835|P|2.5
MSH|^~\&|||||20151217123953.819+0100||ORR^O02|210835|P|2.5
