<div>David,</div> <div> </div> <div>You are right. I was looking at the wrong Java grammar. Also, the C grammar predates what we would consider reasonably fast machines by a few decades. At the time it would have made more sense to "optimize" the comment handling out of the grammar, and use lexer tricks. This might not be an option for SDL's grammar, especially if the Java comment grammar works as advertised.</div> <div> </div> <div>Eric<BR><BR><B><I>"J.
