I think you may have been confused by the posts
about automatically locate files.... these are important for
IDL source code, but when you are dealing with data,
you have to spacifiy the full path.
Normally I use something as
file=dir+filename
such that when I need to move the files somewhere else
I only need to change the dir in one place.
Ciao,
Paolo
