[amibroker] Re: Subscript out of range - why?

["giggollo99" <giggollo@xxxxxxxxxxx>]

Thanks kavemanperth for your reply. Here is my full code:

f[0]=0;
//f[1]=0;
Filter=1;
NumColumns=1;

I have nothing else in my AA window except the above 4 lines of code
(try it). If i uncomment the second line i get an "Subscript out of
range" error in that second line when i run an exploration. I know the
code is not doing anything useful, im trying to isolate the problem,
and understand why i cant index the second element of array "f". 

Thanks in advance,
g
