[amibroker] how do you find the index of an array

["Barry Scarborough" <razzbarry@xxxxxxxx>]

I am trying to use functions which include if-then-else logic but I 
am also using AFL arrays in and out of the functions. If I call a 
function and need to pass the current array index how do I get it? 
Is there a function that provides the current array index. 

It seems that BarIndex() was provided to give this but the return 
variable is an array not an integer. This is not compatible with if 
logic and I get an error when I try to use it. How do I use BarIndex 
to get an integer that I can use to index an array element?

If BarIndex() is not used to provide the integer then what can I use 
to get the current index? I do not want to use a for loop but I can 
if that is the only way.

Also, can functions use global variables, and if so do they need to 
be declared and initialized above the function code?

Thanks,
Barry
