I have been clobbered by using canned routines that set !P. !X, !Y, !Z
system variables for their plots. Then, when I am in the same session
and try my own interactive stuff, these stale values remain. I should
write a routine that I can call that cleans the slate of all set
variables and restores them to the defaults -- has someone done this
already?
