To whom it may concern: The POWERON.OPL source program is a very simple use of system events. Whenever the Psion 3a is switched on, the specified sound file is played. This program is intentionally small, so the sound file name and the name of the icon file to use are hard coded. You'll want to alter the source code accordingly before you translate the program and try it out. You can be the coolest Trekkie on your block by letting POWERON play the enclosed sound file of a Star Trek communicator (the more erudite may find a constructive purpose for this program). Have fun, Matthew Goldsbrough CIS 73241,2533 P.S. Live long and prosper P.P.S. If you think I'm warranting any of this in any way, you're crazy: see my lawyer!
