[gradsusr] Script Problems

[Jeffrey Duda]

Andrew,
I don't think you can define a new variable piecewise in Grads.  I really
wish you could, as I think that is the one big thing keeping Grads from
being the best graphics software out there.  I've wished I could do it many
times.  You'll have to find some other means of viewing that field.
