The system uses the index only on a no-hit. Never touches the data at all.

Subject: I/O count differences
I need an explanation on this if someone would be so kind.
When I chain to a file with a key and get a hit, I fully expect the I/O count to increase by 1, even though it is sort of doing a SETLL and then a READE within the chain process. However, whenever it doesn't find a record it shows no I/O count.
I understand that since it didn't find a record it brough nothing back from the disk and therefore didn't increase the I/O count, but it certainly used resources to spin all the way through that drive disk....Is there anywhere that the system accoutns for this in the statistics?
I see the same results when performing a SETLL, If %Equal, actually even if there is a hit I don't see an I/O count until the READE statement.
