Bifs vs Indicators

Hi List,

 

Just to check timings I ran a small test to see if the use of %EOF bif 

with a read operation would be faster or slower then the use of the classic 

indiactors.  I expected a nice clear black hat/white hat answer but alas the


V5R2 system that I ran on had to surprise me. When run as a batch job, the
Bifs

over an 8 million record file won hands down across various times an loads
of 

the work day. However when the same code was was run against the same file 

interactively, the indicators won.  Don't understand. Could someone explain
this

to me. Time Slice for both batch and interactive was 500. Run priority for 

Interactive was 20 and for Batch 50. Batch DWT was 120 and 30 for
Interactive.

 

I will continue to use the Bif syntax but it sure seems strange that the
same code 

Would provide different results depending on the type of job.
