Thank you for designing this tutorial, well-explained like the everlasting patience of a teacher. Lots of bright colors on black background hurt my eyes but it's my fault I lived a half-century so far.
I don't know, I believe information about the empty string should be given (how it differs from CHR$(0)), and especially caution using it with "ASC()".
If there's going to be information about QB64-only functionality, also indicate the second parameter to "ASC()" has to be within range of the string in the first parameter, for the same reason.
This is something a beginner could trip with. Take it from me, from programming on the Color Computer 2 then 3, and becoming disgusted M$QB also returned "error #5" for <code>ASC("")</code>.
