Hi,

Thanks all for your replies.
I already found the RBIT-instruction. I also found out I need to study 
the arm assembly language ;-)

But how do I get my variable ? Is that in some register ? Is there any 
documentation about such things ? Then I can use inline assembly.

Thanks,

Koenraad Lelong.
