Yes. There is no change for all of the expressions, apart from the function. For the function, you'd use the standard "if" operator for the first "if" expression, "elseif" for the second and third "if"s and "else" instead of "otherwise".
If you have Prime 3.1, then you can import the M15 worksheet using the provided xmcd converter (note that the converter may use "alsoif" rather than "elseif").
