Good question - you don't have to issue GO TOP. SCAN does an implicit GO TOP unless you use SCAN WHILE ... or SCAN REST.

One more common gotcha: the ENDSCAN does an implicit SELECT . So overall, the SCAN is roughly equivalent to:

GO TOP
DO WHILE NOT EOF()
    [enter loop commands here]
    SELECT [whatever the cursor was when the SCAN was issued]
ENDDO
