Thanks, Wayne and David. The information is very helpful. Craig's
value_locate.pro still doesn't work since spl_interp is not built into
GDL yet (as far as I can tell for version 0.9). I will just wait and
use IDL instead.

BTW, I just started to use GDL and IDL student version the same time.
My hope is by using GDL, maybe I can force myself to know more about
IDL in addition to just use "plot,x,y..."

Best,

Zhonghua
