The semantics of an expression is the value of an expression. Although if I had to imagine using one of those two sentences, I could vaguely imagine using the former? As in "what does 1 + 1 mean?" It means "add one and one together, the answer being two". But, even in that case, I wouldn't make it a blanket statement. You have to contrive an example where you would use a statement like that and it isn't particularly natural. Most importantly, it isn't something general. This is as close as I can imagine coming: "In a value oriented language, the meaning of an expression is the value of an expression". So, I heartily agree with our esteemed moderator. Don't believe everything you read. -- ****************************************************************************** Chris Clark email: christopher.f.clark@compiler-resources.com Compiler Resources, Inc.
