- * InputLock V1.0
- * By Preben Nielsen
- *
- * This program is intended as a help to Amiga-users who has cats
- * or other pets (or children) that messes with the Amiga as soon
- * as you leave it for a second.
- *
- * It installes an input-handler which lets you lock the keyboard
- * and mouse by pressing a few buttons (currently LALT-CTRL-'l').
- *
- * Once installed, the program only uses 190 bytes of memory. To
- * remove the handler simply run the program again.
- *
- * NOTE: There's no need to 'RUN' or 'RUNBACK' this program from the
- * CLI. It terminates immediately.
- *
- *HISTORY
- * Made with Hisoft V2.12
- *
- * V1.0 11-Apr-91: First attempt. Works of course
