>Hi,

>I ran into a problem today that was caused by the fact that in one of the form's LOAD method there was SET EXACT ON. So I started checking further and found that a few other forms have SET EXACT ON in the LOAD. I am not going to ask why I put this code there <g> (who knows). But in general do you recommend never to have SET EXACT ON as global setting (in LOAD) and only set it ON in places where it is necessary and then reset it back to OFF?

It doesn't answer your question, but I can't recall ever using SET EXACT ON. I always use the == operator when I need an exact match.

In general, if you're doing something "unusual" you want to minimize the amount of time it's in effect e.g.
lcOldSetExact = SET( "EXACT " )
SET EXACT ON

* Stuff that requires SET EXACT ON goes here

SET EXACT &lcOldSetExact
That said, SET EXACT is scoped to a datasession. So, if your form uses its own datasession, when you close it the SET EXACT no longer has any effect. If it's OK for SET EXACT to be ON for the duration of the form, it might be OK to leave it in the .Load.
