COL
The COL function returns the number of columns in an array as it is
currently dimensioned. If it is a vector (a one dimensional array), the
number of columns is one. Otherwise, the number of columns is the size
of the rightmost dimension. The result is an integer value by default.
Syntax

Parameters
