A web site that you can paste stuff and then provide a link(url) that
others can use to view it.
You can usually specify the code style

I'm not familiar with FORTRAN, and since I'm not completely sure what you're

My guess is that you're not getting the curve because Z is only defined to one
decimal location (1/10th) precision and probably needs higher p
