Question:Procedure inputs??

Hi all,

I read the help on using parameters, then I tried to modify the example


f := proc(a, b, c)

    if _params['b','c'] = NULL then
    a
    elif _params['c'] = NULL then
    a + b
    else
    a + b + c

    end if

end proc:

I can't really spot where it went wrong, but it just wouldnt execute as I would expect...

What's really the problem?

 

Thanks!
