/* This function has global scope within this file (module). It is represented

 * if it is referenced by any other function.
 */
static void some_function()
{
    /* These "local program variables" are of no interest to the linker 
     * since they are not visible outside the current function, so no other 
     * part of the program can possibly reference them.
     */
    int a, b, c;

Local Linker characters are defined and refer exclusively to the module.
