>>I am trying to confirm a point iro the working of mdot: if I have a file with 10 fields and 100 records and I need to scan through this file and inside my loop I reference 10 variables then will VFP need to lookup and resolve 10 vars x 10 fields x 100 recs = 10,000 field/variable references? Would using mdot avoid the need to perform 10,000 field/vars lookups?

But how significant this effect is, compared to the overall execution time, and whether other factors may actually act in the opposite direction, is hard to tell without an actual test.

Hi Hilmar. Thanks but I am not asking if it is faster or not. The question has a definitive answer as to whether these lookups are performed or not. Someone knows for sure whether this is the case or not.
