Thanks for the help, Bob. Hopefully you can get your Turbo Pascal program back or get the Win32 program out soon. :) Just one suggestion: a Win32 console (command line) version will be more helpful than a GUI program. Actually I was thinking of writing a simple C program to change the Hex file and use it within a batch file with procmd. But my software programming is really lousy and I am also lazy to learn.
