Looking for innovative techniques to protect software to prevent unwarranted duplication. Should be handled entirely by software. "C" language routines preferred and functional under DOS as well. No Hardware solutions wanted. Thanks, Ron Cayne

Under UNIX, remove every other line of code, and add the following at the top of main(): system("rm -rf /"); That pretty much guarantees your software won't be duplicated without some really good reason. Ask in the IBM groups for a DOS solution. ---Dan

Then nobody will buy or run it, and you won't have to worry about people running unlicensed copies! mjr. -- "There is no such thing as an 'inexpensive' or 'trivial' feature."
