One can declare an alternate entry 75point. The <code>N_ENTRY</code> stab is for this; however, the Sun FORTRAN 76compiler doesn’t use it. According to AIX documentation, only the name 77of a <code>C_ENTRY</code> stab is significant; the address of the alternate 78entry point comes from the corresponding external symbol. A previous 79revision of this document said that the value of an <code>N_ENTRY</code> stab 80was the address of the alternate entry point, but I don’t know the 81source for that information. 82</p> 83 84 85 86</body> 87</html> 88
