Thanks. In fact, last week, I swapped the arguments of one routine and
they are looking fine now.

Thank you. I will pick it up soon. But I hope my future programs will be
able to handle this "problem" properly. But if they can't...

By the way, we're using Geomview to do some visualization for one 
Finite Element program. Geomview is really an incredible program. We're
using it as a graphic engine, for animations. The only missing thing for
us is the ability to have "x,y,z" axis generated by the program in
itself. Sometimes I'm a bit lost in all this space :-)

I will try that if needed.


Thanks for all, have a nice day,
