Re: Expensive op codes

Firstly, thanks for the info.  It is interesting, and not at all the 
results I would have predicted excepting the results obtained when you 
removed the K.

What I am still curious about though is: What would have happened if you 
had used the cycle to process the same records?  No READ, no READE, just 
InputPrimary on the keyed file.

Both test runs used OVRDBF FILE(ECLL02) SEQONLY(*YES 341)
Both test runs read the entire file by key.  Program 1 used READE, program 
2 used
READ and compare.

Program 1 elapsed time was 33 minutes 38 seconds.
Program 2 elapsed time was 12 minutes 38 seconds.

I think I will be using the READ/Compare model versus the READE model 
whenever
possible when I need to read by key.

By the way, reading the non keyed physical file with the same OVRDBF only 
took 1
minute 22 seconds.
