Beginner LISP question

David, that's a very good point on getdist. It's more general-purpose since
it lets you denote a distnace in various ways, including picking two points.
Whereas getreal only allows a numeric entry. I've had to change a few of our
old (architectural) routines from getreal to getdist, because getreal won't
allow a foot-inch response.

 

Tom, there are few instances where (getreal) is best choice for user
input. i.e. scale factors, angle in degrees, sequence hashes. By in
large I use (getdist) much more. -David
