Bonjour Alain,

Thanks...

I just found a way to make it work.

I changed my code and put R_V0 = rvalue & $03. But, to be honest, I don't understand why it works now.

Before opening this thread, I read lots of other threads about this subject. I've also been reading the Compiler's manual. I read this "Var is used both as the seed and to store the result" but my english is to poor and I don't understand the correct meaning of the word "seed" (graine - in french) here.

Could you explain this command in other words please?
