I have completed a program that enciphers plaintext into a K2 simple substitution cipher. It is quite interactive and will print the results if your printer is in the PT1 port. If anyone is interested in having a copy, let me know at archieb42164@yahoo.com and I will e-mail you a copy. I plan some other projects in the near future such as a master program that will allow you to choose either a K1, K2, K3, or K4 key and can either print the results in standard word length or in 5-letter groups. I use the PowerBasic console compiler to compile my BASIC code. I can do just about anything that I want with it.
