1.0.0 (B10) u16

Description

This is what SHOULD happen when these special characters are contained within strings being printed:

Chr$(8) (backspace) should put the text cursor at the previous x position.
Chr$(9) (tab) should put the text cursor at the next TAB position.
Chr$(10) (line feed) should put the text cursor at the current x position on the next line.
Chr$(12) (form feed) should have the same effect on-screen as Chr$(13).
Chr$(13) (carriage return) should put the text cursor at the beginning of the current line.

Right now, all of these are ignored.

Tab (Chr$(9)) is now working, but the rest still fail.

Chr$(8), Chr$(10), and Chr$(12) move the cursor forward 1.
Chr$(13) does nothing.

Tested this again 2/3/21 and still not working.
ie: For example, in relation to just the chr$(13) and chr$(10).

Still in Amiga mode, Chr$(13); will only do CR, and Chr$(10); will only do LF

A real world example of this on an input char routine.

Ok, When I detect how far using the text curs moves with X curs in my case 19 characters, I then decide to move down a line, so I do a print chr$(13) or and in combination with a print chr$(10) which moves the curs down left to start as it should and down a line.
What happens then is, the next character input again jumps back to the end of the previous line and then, the next char goes back to the start of the next line as it should again.
The Curs in Amiga mode anyways, does not actually go there at all at this point in time in reality.
