 That could work nicely - another idea is use Scott's FTPAPI service 
program - you then control the pace in your CL even more easily, perhaps.

Cheers

After researching and testing and troubleshooting on the IBM i and checking out the script............to no avail.  Oddly the script ran fine when we ran it manually but we could not get it to work through a submitted job scheduled to run late at night.  Everything was exactly the same for the script used to FTP when we did it manually and when the job ran as a scheduled job.

It was competing with a very large amount of other FTP traffic.  They said they cannot stress this enough we need to slow it down.  Based on the traffic from the FTP Logs and the Network capture.   The IBM i is jamming the data through.  They asked the script be changed to slow it down to fix the problem.
