Yikes!  Why did you pick FTP for this?  This sounds like an absolutely 
ideal candidate for HTTPAPI on the remote end, and CGIDEV2 on the "our 
server" end.

No idea. I would guess that the program is creating the "I'm Done" file 
before it flushes all of the records to disk, but that's purely a guess 
and you've already said that you don't think it's the answer.

Is FTP_get() returning an error?  If you look at the log/job log, is it 
sending you the proper response code when the file is received?

I'd suggest HTTP.  HTTP always works as a request/response situation. 
You'd have the remote iSeries request a particular URL on the server that 
points to an RPG program. That program does whatever processing it needs 
to and returns the file straight out to the HTTP client.  The HTTP client 
saves it to a file on disk or whatever you need.

HTTPAPI works nicely from the "remote computer" and CGIDEV2 may work 
nicely on the server machine (depending on what you're doing) to make it 
easy to return the document.
