Format .------------. V | >>-FUNCTION ORD-MIN--(----argument-1-+--)----------------------><
If more than one argument-1 is specified, all arguments must be of the same class with the exception that the 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 least value in the argument-1 series.
The comparisons used to determine the least 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 least value, the number returned corresponds to the position of the leftmost argument-1 having that value.
