What is the best programming language to start with?
Is it worth it to learn DOS?
Where are the best free sources of learning material for these kinds of things?
I know of w3schools.com, that's about it.

This is what I want to know and have answers to or direction, please.

Thank you.

1) There is not a best language to start with, it is usually a matter of opinion and preference.
2) Yes and No, it depends what you want to do.
3) There are many, again it depends on your targeted area.

My personal recommendation for starting programming is C/C++ or C#. I taught myself QBasic when I was in 5th grade. Learned HTML 6-7. Took a VB Class in High school, but I already knew more than the teacher.

I am mostly self taught.

HTML isn't really programming by itself, but W3 Schools is probably the best quick resource for most things web related. HTML, Javascript, php, sql, etc.
