FOR EACH customer BREAK BY location:

IF FIRST(location) THEN
DO:
// This code will be executed on the first record in the loop.
// Will only fire one time.
END.


IF FIRST-OF(location) THEN
DO:
// This code will be executed on the first record of each location.
// Therefore if there is 30 locations, then it will fire 30 times, on the first
// customer record for each location.
END.


END.
