I got imprinted with WordStar back in the early 80s. So much so, that when I program today I use those same text-editing command-codes. So I can jump seamlessly from programming on CP/M, Linux or even MSDOS. Frightening, isn't it? <grin>
A bunch of us got those commands imprinted on our brain by using Turbo Pascal, even though we didn't use WordStar.
