Re: RPG and Threads

Does anyone have a simple program example (or know where I can find
one) for an RPG program that creates thread jobs? I am wanting to
know if it is possible for one RPG program (or CL) to start 4 or 5
threads, and each thread would process one part of a file, instead of
having one program process the file from beginning to end. This is a
read and summarize application that is being converted to SQL, but
even with SQL, it takes a long (7+ hours) to process the whole file.

The database with the SQL can already do the [effective or actual] threading, if allowed to; no need to effect that at the application-level, if the database will do so instead. See the Change Query Attributes (CHGQRYA) command for the Parallel processing degree (DEGREE) parameter for the "Input/Output (I/O) parallel processing" capabilities; also Symmetric Multiprocessing (SMP), but only if that optional-install\purchased feature is installed and licensed.
