** This program was written to strip out all the Form Feeds in text
** files. I hate it when people waste my printer paper! I also like
** to post News Letters for my Users on my BBS, and imbedded Form
** Feeds screw things up bad when trying to view the News Letters
** (like FIDONEWS!) Hope you like it!
**
** KILL FORM FEEDS v1.1 by Jerry Gore (Public domain?)
** Version 1.2 by Erik VanRiper on 12/22/91 Public Domain!
**
** This is basically a complete re-write.
**
** Reads a text file and makes a duplicate with NO Form Feed
** characters! The duplicates name will default to temp.txt. Form
** Feed characters are replaced with a space (decimal 32).
**
** Usage: KILLFF FILE.TXT [TEMP.TXT]
