  66. <p>Some languages, like Fortran, have the ability to enter procedures at
  67. some place other than the beginning. One can declare an alternate entry
  68. point. The <code>N_ENTRY</code> stab is for this; however, the Sun FORTRAN
  69. compiler doesn&rsquo;t use it. According to AIX documentation, only the name
  70. of a <code>C_ENTRY</code> stab is significant; the address of the alternate
  71. entry point comes from the corresponding external symbol. A previous
  72. revision of this document said that the value of an <code>N_ENTRY</code> stab
  73. was the address of the alternate entry point, but I don&rsquo;t know the
  74. source for that information.
