Re: Need Help On a Problem

Well, the reason I did this is I am getting this data directly from a
data queue, then I just directly pass this information to another
program to process. I didn't want to have this first program be overly
complicated because it is running in QINTER, so didn't want to take up
a lot of CPU. I guess, that sort of bit me. I will have to figure out
how I will handle this then.
