Getting Started in Computer Programming Questions

Last year I learned my first computer program language by accident. I hand copy texts using archival ink to imported artisan paper/scrolls from india and nepal so I can get a feel for how big historic texts actually were, and saw something about Lambda Calculus and jus started copying it all down. It was apparently the first programming language ever developed. I don't know what to do with it otherwise. I vaguely recall programs I believe called AAB++ and Haskell are based on it, but when I looked at Haskell you had to know C++ too.

I like logic in philosophy and know there are database languages for induction.... but I'm uncertain where to get my start. I want to do it on a computer, not a android app, preferably free and at my own pace. Not some coding bootcamp. I have no idea how to load it up on a computer though. Clueless.

What options exist?
