1) To remove ambiguity and prevent unintentional errors. This one is important. ie:

kod = 1
select myTable
locate for code = kod

or select * from myTable where code = kod

and don't be surprised if it doesn't find any records when you're sure there is one with code=1.

2) Performance. Much less important but may sum up to minutes difference.
