Thank you for reply.

I still haven't solved that sscanf problem event with C strings.
I tried to replicate the problem with a new project, and it worked fine.  
Still I used exactly the same code !

Can anyone take a look at the code, here is the link for the projects  
http://adogames.com/programming/problem.zip (One of them uses - with  
problem uses Derelict )
