Using DATA-GEN to generate JSON

I have a multi-dimensional data structure (array) that I am trying to parse
into a JSON string using DATA-GEN. The Generator is MDRFRAME(GENERATOR),
basically YAGL.



The data structure/array has nested arrays.



When DATA-GEN executes, it crashes. From the error message, it is crashing
on a unused array element. Only 1 message is reported in the job log where
the problem appears to be an unused array element in a nested array.



I believe the generator should have ignored the unused elements.



Does anyone have suggestions on how I can identify the problem?



Thanks
