And of course, your main function should end with "return 0;" or "exit(0);" (the latter requires "#include <stdlib.h>" at the top). By the way, I recommend you get a copy of the C standard and use it for reference. You can buy a digital copy (PDF) at http://webstore.ansi.org/ (Search for "9899-1999"), it's $30. Alternatively ask Google for "C99 draft" to get a free copy of a draft of the standard, which isn't very different from the final standard. You can also buy a hardcopy of the standard (i.e. a book), but it was ~ $300 last time I looked. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
