GREAT !! Simply GREAT !!!!

Thank you very much Greg. 

I was missing some knowledge to build up something like that and my printed manpages were not up-to-date as the online ones ..

Your help opens me new horizons ! Thank you very much !

And many thanks also to all the people who helped me with the rpict progress stuff (just giving thanks here to not send to much mails to the forum) !

.Sorry about that.  It looks like a mess, but basically I'm just  
.checking intersection values against the ones you get from your  
.orthogonal view, and I need rcalc for that.  All the -if's and -of's  
.make it run faster, but aren't really necessary.
