If Rlock() use to lock then how the syntax or the samples of it...
for instance i have records
===========
N J
===========
| 1 | A
| 2 | B
| 3 | D
| 4 | D
===========

I want to lock record no 3 and want to change or edit "D" with "C"
is it correct if i use :

RLOCK(3)


then if other users want to make a change to that records also they have to
check

If Rlock(3) then
....
endif

is that correct also...

please give me solution about this cause i really confuse of it...

thanks....
