[Scilab-users] Punch a hole into a facet

[Jens Simon Strom]

Thanks Samuel,
I would use Vers. 6 if I could use variable names containing an 
exlamation mark ("!"). All my several hundreds of function names contain 
that character. The bug is announced to be fixed  - but is it also fixed 
if I download the recent Version of Scilab?
Cheers
Jens
