Encryption programs for the A8? in Atari 8-Bit Computers Posted Tuesday at 01:03 PM Found the listing in the PDF of ST-LOG #32 at Atarimania. Looks pretty simple to model a BASIC XE (or Turbo BASIC XL) program after it using the XOR function in either of those languages. Thanks for the suggestions and especially Rybags with the XOR suggestion (since it is easy to incorporate into a BASIC program). Interestingly, the example of using XOR in the Basic XE manual is wrong! Says 5 % 39 = 32 and is actually 34.
