Thank you for your Article Parsing JSON using RPG with Scott Klement's Port of YAJL - Part 3. It had the exact answer that I needed for my project. The vendor that I am getting a file from puts an unnamed array inside a file and sends that JSON file. Using your vehicleList = docNode example, solved my problem of the missing array name.
Thank you, thank you.
I'm glad it helped! I've been doing a lot of JSON both building and parsing and hope to have more examples soon.
