Dear Haje,
Thank you so much! Your information is very helpful to me
because I didn't know IDL has a way to call C.
I didn't mean to annoy people here but I was desperate to
know some how-tos. I do appreciate your suggestion with
a good references book. I'll take that approach.
gratefully,
hyunsook
