Re: How to optimize COPY *ADD

I know that it is looked upon with scorn, buy why not make the file an
Input Primary with no key?
1)  You're not doing the keyed read
2)  And notice that little compiler message 'RPG handles the blocking for
you'?  I've found the compiler much more efficient in determining blocking
on a primary file than I've ever been able to duplicate in CL.

Lot's of other good suggestions out there though!

Dimitri,
I haven't tested this for several releases, but an RPG pgm used to be a LOT
faster than cpyf.
Delete and recreate the LF's if you can.
Don't use the "K"eyed read, do a ---- Read-DoW Not %eof-Write-Read ----
loop
and increase blocking factor in the CL.  You can cut down that time
significantly.
