Custom function in Flash 8

Using function-defined functions in Flash 8 is similar to PhP, for example:

// Return a large number of two numbers <br/> function max (A: Number, B: Number) <br/>{< br/> return A> B? A: B; <br/>}< br/>

If the parameter has no type constraints, you must pass the correct type parameters when calling this function; otherwise, "undefined" appears ".

If a parameter has a type constraint but the type of the passed parameter does not match, the "Type mismatch" error occurs during running ".
