Or, pass an argument in of the name of a variable being restored:
pro restore_it, my_var
restore,'my_var.sav'
end
then on return my_var will have been set.

Hi
The variables are properly restored, but only "inside" the procedure.
Once you leave the procedure, they are discarded.
To access them you have to either return the variables from the procedure
(PRO plotprecip, var1, var2, var3) or declare them as global variables
(COMMON).
