Herman,
I also initialize my variable to 0 ..... but I don't want to do it the
"normal" way ...
if I initialize to Null, (or anthing else) then AB will initialize to Null
for every time the code executes.
Last_BuyState = Null;
IsNull(Last_BuyState) ... the result will always be True.
I am trying to have a scheme where I set variables only once when AB is
first turned on
if (IsNull(Last_BuyState)
{
//initialize variable
Last_BuyState = Null;
}
... else no action
Any way of working that?
