I don't think you understood my reply.
I was not refering to the "stock arrays" or any array based on the stock arrays (which is what barcount is useful for). I was refering to an array constructed independantly of the stock arrays:
In the following example x contains three elements, how do we get the element count (in AFL) for x ?
i.e.
x[0] = 1;
x[1] = 2;
x[2] = 3;
In Visual Basic we can perform lbound(x) and ubound(x) which returns the lower and upper bounds of an array, in AFL I don't know of any function that performs a simular job (there maybe but I am unaware of them).

William,
AFL would be a miserable and unproductive language without counting
the elements of an array !! [I am curious if there exist any T/A
language without this property...]. I didn't understand your reply.
