BASIC+ automatically allocates space for a 0 (zero) element when a matrix is dimensioned. That is, one more element is always available to receive data than is dimensioned in the Dimension statement. It is a single element, not a row or column. The data in the 0 (zero) element can be accessed by using a 0 (zero) subscript:

Matrix(0)

/* Matrices named V, K, and R; each to contain 11 elements.
