Any interaction with things outside your program should use TRY...CATCH, since you can't foresee what can go wrong. In the case of opening a file, for example, you might have the following problems:
  • Filename is wrong
  • File is R/O
  • No access rights
  • Local or network disk not available
  • Error reading file
  • ... and probably a few more.
    Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
