How to judge a Function's parameters ? [message #66273] Thu, 07 May 2009 14:51

Hi,folks,

I created a function 'RectArea' to calculate the rectangle area, and
two parameters, side a and b, are needed when the function is
employed.

I want to do something like this: if a and b are omitted by the user,
then the function will use the default values.

But, How can I judge that the parameters are omitted?

Thanks

function RectArea,a,b
return,a*b
end
