external call

[Frédéric Mabille]

Hi
I actually try to execute an external call in Scilab (mac os), with no  
success ^.

My programm produce a 'myfile.pov' file (this is a text file) used by  
the ray tracer povray.
Actually, i used on a terminal the synthax
 >povray myfile.pov
to produce a myfile.png image.

I would like to include this commande in my scilab file.
i've try :
 >host('povray myfile.pov')
and
 >unix('povray myfile.pov')

but no-one give me the myfile.png result.
Could someone give me idea ?

thx
Fred
