Hi, Bill

If the SQL Server can export the file into an ASCII fixed length or 
delimited form on itself, then the iSeries could read that through /QNTC. 
Of course, the size makes that prohibitive, too. You'd use CPYFRMIMPF, not 

CPYFRMPCD, which has to be in QDLS, and has to be in 8.3 naming, as well 
as 
being relatively slow.

Or, instead of copying into a PF, RPG (ILE at least) can directly read the 

IFS file and work with the data - it involves IFS APIs - see the API 
manuals. There are folks on this list with examples, I believe.

/QNTC lets you mount directly to NT/2000 file shares - very cool because 
it 
takes no space on the iSeries, and no need to map anything on the SQL 
Server box.
