Ok, forgive me for the english mistake : I use either type cast or type conversion to mean the same thing. I will take care in the futur. But I'm still not sure about the assertion that it is context free (while, Ok, the AEM does not tell it is LR(1)) If it need name resolution to figure out what means the construct, this is not a context-free grammar. Is this construct the only one of the grammar which is not context- free, or is there some others ? It appears to be the only one of the kind, but I'm not sure. Yannick
