Re: Unsecuring old HP Basic software

Eons ago I wrote an “unsecure” utility for HP BASIC. It’s simply a matter of flipping a bit at the beginning of each program line. It’s easy to see how the SECURE function works by writing and storing a one line program, looking at the stored file with a hex editor, then securing that line, storing the new file, and comparing it to the original.
