why is JB saying my function name is invalid?

[kelvinkoolohm]

            x=3

            p=v(x)

            print p

            end

function    v(m)

                v=m

            end    function

no matter what columns I put the function statements in,

JB halts at the first line of the function definition and says

"invalid function name".

Why?

I just copied your code from forum and it works

Do the same
Does it work?

Have you tried restaring BASIC, just for the case it broke?

I suspect you have some unprinted chgaracter (like Ctrl-D) somehow sneak in.
