TIB: Re: Re: RE: Re: x=b




Why does any of this need to be done at all?  Why don't you just set it to Parametric mode, and
graph this equation:
xt1=(value of vertical line here)
yt1=x

That way, you are able to use the Trace supplied with the graph mode without the neccessity of
making a program.
