>Obviously we can use FOPEN() to retrieve an error code, and FERROR() likewise. However there seems to be no way to access a file which was previously opened... and no way to close it, or otherwise re-Open with a new Handle.
That's right, if you accidentally left it open, you are in trouble. Therefore, you should apply clean programming, and close the file as soon as you don't need it any longer.
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)
