Use the dim() function;

do i=1 to dim(score);

Syntax needs a bit of attention

6            k = dim(a{*});
                        _
                        386
                        200
                        76
ERROR 386-185: Expecting an arithmetic expression.
ERROR 200-322: The symbol is not recognized and will be ignored.
ERROR 76-322: Syntax error, statement will be ignored.
