Terry,

Since I use a field/variable naming convention that prevents conflicts I very rarely bother with adding m. The only place I ever worry about the it is if there are enough iterations of a loop to make a noticible difference in the execution time.

For instance, when assigning values to a var, it's no use in distinguishing between a table field and a memory var of the same name, because one always uses "REPLACE" for fields anyway. Of course, if there are a field and var of the same name (and assuming the field's table is currently selected anyway) then it is useful for distinguishing in cases of comparison. But that's the only advantage I can see.
