It can probably be done. But why bother?

The notion advanced earlier of having a server job that can spin off as many jobs (i.e. threads) as needed to process the data based on the system load at the time works just fine.

RPG was not designed to be a threaded language and even to safely call it from a threadsafe language requires care.

Use the tool for the job.

I did look into multi-threading for RPG within one job but didn't find any
good examples. I think it's doable. I think the best way to start
multiple threads in one job is to create a Java process to call RPG
programs and start threads in java, of course make sure rpg programs are
thread safe.

Does anyone have a real world example of this? A link or anything?

I'm trying to decode a very large number of element JSON using DATA-INTO
and it using YAJLINTO as the %parser. Each file on the IFS is one
transaction/message and can have over 3k individual elements. Each message
has 2 big blocks of elements split about 50/50. Each half of the message
end up writing out to separate group of PFs. Can I process each half
simultaneously and not have to submit a ton of separate jobs? Just trying
to speed the process.

Any thoughts would be appreciated! Thanks!
