Wow, thanks a lot again! Very simple, but very clever. I didn't think
about to change the directory. But this is the simpliest way to get
just the filename! So i wish you to have a nice day and thanks again,
david!

By the way, i've bought your book IDL Programming Techniques, 2nd
Edition. It is really fantastic! I learned a lot, and it's also a big
help with widget programming. I still use it as my reference IDL book,
because you describe things on a very simple and unterstandable way!
It would be also very great, if you could also describe the
call_external routine as well as make_dll to implement some simple C
code in IDL. Maybe in the 3rd edition? :) Because I didn't find any
book where it was explained clearly. Of course, IDL doesn't need any C
functions. It's more powerful, but I had to control my Camera via a
frame grabber. And this was only possible with C.. Ok.. thanks and
bye ..
