It is not a "mainstream" definition of identifiers. It is, as I said earlier, some aggressive mechanicism with the functional part of the language abruptly removed. If it is indeed not some of your own definitions but a CS school definition I am really curious where does/ did it reside. I couldn't find such even in Berserkeley which is always a place to look for some new weird stuff :)

And there's the C++ standard (which you won't have seen because it costs money). "An identifier is an arbitrarily long sequence of letters and digits" ... And there's the O'Reilly book "C# Essentials". "An identifier must be a whole word" ... John -- John Harris

Which is the sort of VKesque non-sentence that undermines credabilty. Richard. |
