I beleive that since PERFORM doesn't return anything, it sets the FOUND
variable to at least indicate whether it did something. OTOH EXECUTE
can return something so it doesn't need that.
It's a bit wierd, but I think later versions changed EXECUTE to set
FOUND also, just to be consistant.
Have a nice day,
