Thank you! Anyway what I was really asking was a "$" (or whatever other symbol) in place of ":" for sum, that is a notation like
myarray_col[12$16]
would give the sum of all values from myarray_col[12] to myarray_col[16]
Anyway, I was reading that multidimensional arrays must have matching dimensions (that is, they can't be, for example, [5][9]).
Is this right? Why is that?
Thank you
