Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

─────C/C++ Language─────────────────────────────────────────────────────────
 
     A C or C++ identifier must begin with an alphabetic character,
     either uppercase or lowercase, or an underscore (_). After the
     first character, an identifier can contain any combination of
     letters and digits. A single identifier can be up to 247
     characters in length.
 
     Both C and C++ are case sensitive; they treat "filename" and
     "FileName" as different identifiers.
