Symbol


   An assigned name for a value representing a constant or the address
   of code or data.  There are four types of symbols used by the linker
   defined as follows:

      . Absolute symbol: A constant

      . Relative symbol: Address of code or data

      . Public symbol: accessed by modules other than the module in
        which they are defined.  Public symbols are used to share
        procedures and variables between modules.  As such, the relative
        address of a public symbol is assigned by the compiler during
        compilation.

      . External symbol: A public symbol not defined in the current
        module.  Generally, these are references into CLIPPER.LIB or
        EXTEND.LIB, but the compiler generates them whenever there is a
        procedure or user-defined function referenced but not compiled
        into the current module.
