Re: YAJLGEN and Supposedly Simple JSON

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Stephen,

You can't use countprefix to count the outermost element of a JSON 
document.  Instead, you'll need to use position 372 of the program 
status data structure to determine how many elements there are.

dcl-ds pgmStat psds;
  num_jsonDoc int(20) pos(372);
end-ds;

Good luck
