>>-FUNCTION ORD-MAX--(----argument-1-+--)----------------------><

argument-1
Must be class alphabetic, alphanumeric, national, or numeric.

All arguments must be of the same class, except that a combination of alphabetic and alphanumeric arguments is allowed.

The returned value is the ordinal number that corresponds to the position of the argument-1 having the greatest value in the argument-1 series.

The comparisons used to determine the greatest-valued argument-1 are made according to the rules for simple conditions. For more information, see Conditional expressions.

If more than one argument-1 has the same greatest value, the number returned corresponds to the position of the leftmost argument-1 having that value.
