I've done this a few times. Works like this:
SET(LOF:key,LOF:key)
loop
if access:loen_fast.next() then break.
! Do a lot of things on this loen_fast
HldPos = Position(LOF:key)
LOF:field2 = 'Something in this record of loen_fast'
set(LOF:Key2,LOF:key2)
loop
if access:loen_fast.next() then break.
!Update some Loen_fast records
end
reset(LOF:key,HldPos)
access:loen_fast.next()
end
The trick is you need to issue a next after the reset to get back to were
you were.
