RDI 9.6.0.5 - DBGE0001E Expression DS is too complex

Hi Jon,

Thanks for this... your response got me thinking about how to address this, and even though I don't have the answer, I'm thinking of different techniques to be able to at least verify the parsing (and structure definition itself) is successful.

If I recall correctly this is not an RDi limit but rather the system debugger. I _think_ there are techniques to get round it but not sure if they are applicable to RDi.

Don't have time to research it right now but I suspect if you check the RPG and/or Midrange forums you'll find an earlier discussion.

One quick fix would be to create a duplicate of the structure you want to debug (or a simple char field of appropriate size) and base it on the address of the nested Ds you want to view.

I'm attempting to debug newly written code that is parsing JSON into a multi level data structure and running into this message.
Is there a limit that RDi can traverse into a data structure?

Not the actual code, but here in order to maintain the structure of the incoming document, here's the basic structure.
The DBGE0001E message appears when attempting to expand SectionA.

dcl-ds DS qualified;
field1 varchar(10);
field2 varchar(10);
field3 varchar(10);
field4 varchar(10);
dcl-ds Section1 dim(2);
field1 varchar(10);
field2 varchar(10);
field3 varchar(10);
dcl-ds SectionA dim(10);
field1 varchar(10);
field2 varchar(10);
field3 varchar(10);
dcl-ds Section2 dim(2);
field1 varchar(10);
field2 varchar(10);
field3 varchar(10);
dcl-ds SectionB dim(10);
field1 varchar(10);
field2 varchar(10);
field3 varchar(10);
end-ds;
end-ds;
end-ds;
end-ds;
field5 varchar(5);
end-ds;

Thanks,
Doug
