 Re: PLOT function from BASIC

Yes, I said we can also READ the location:
>When called with the carry flag set, this routine returns the cursor position. (from the US Plus/4 PRG, page 315)

However we can also PEEK(202) for the column and (205) for the row. This saves a BASIC programmer (like me) from having to learn machine language routines.

As I pointed out above, using PLOT destroys any text-screen windows you may have set (with ESC-T and ESC-B). By using CHAR and the PEEKs, the text window is preserved.
