This is my text:

function grade=switchletgrade1(quiz)

if quiz<0 ||quiz>4

grade='X'

else switch quiz

case 3

grade='B'

case 4

 grade='A'

        otherwise
            grade='C'
end

end

end

Your code works error-free for me.

Is it possible that you are inadvertently calling a different file with a pre-debugged version? Does the command

 >> which switchletgrade1

give the file location you expect?

I had an autofile version of the m-file when I deleteed it it wroked.

Here was a link which showed me where to turn off auto saving. Maybe I called the autosaved file? Said something about debugged in the link over if that was what you meant. anyway it worked!
