If I'm not mistaken, he can have names for DDM files that differ but
point to the same-name PF on different machines, right? Then he can list
them all in his RPG and open them all if he wants. You still have to
read each one on its own, but this seems like a VERY simple thing to do.
And simple makes for much better maintenance down the road.

Legacy-phlegacy!! Go for DDM!!

Okay, it sounds like SQL may be the best way to retrieve the remote data in this case. Whether you use SQL / DRDA or RPG Record Level Access / DDM may also depend on how normalized the remote files are. But, it sounds like SQL / DRDA may work best in your case.

Nathan -

We are gathering inventory balances and cost from the appropriate JDE files
in all affiliates.

This information, once gathered into one comma or tab-delimited file in the
special environment, will then be FTP'd to be processed by a BI application
running on a PC server. Once the data is successfully obtained from /all/
52 environments, the client (another department within the company) wants
the aggregated data sent all at once, not 52 separate times...

Steve,

What would be the purpose of transferring the data to the "local" system?
Why not just read remote data and output it to the client?
Are we talking 5250 or browser?
Would the new application be updating remote data, or just inquiry?

Nathan.
