[Scilab-Dev] Problem with interface.

[Jonathan Blanchard]

Thank you for your reply but it give the same result. First I assumed
you meant l1 on the printf line because l2 does not exist.
Secondly it does the exact same thing. But if I remove the printf
line, Scilab complain about a bad call to createvar :

TestGetRFAttenuation: bad call to createvar! (1rst argument).
