Re: Odd VFP DO WHILE Behavior

See HELP - topic NULL. And careful with using null anywhere.

Jack Jackson napsal(a):
I noticed the following odd behavior (in VFP9).

LOCAL xx
xx = .NULL.
DO WHILE xx
...
ENDDO

The loop code is not executed, which is what I would expect.

LOCAL xx
xx = .T.
DO WHILE xx
xx = .NULL.
ENDDO

The loop code is executed forever. Doesn't that seem wrong?
