PLOT - (Kernal $FFF0) When called with the carry clear, sets the cursor position. The new cursor line number should be in .X, the new column should be in .Y; the screen window is returned to the default 40x25 screen. When called with the carry flag set, this routine returns the cursor position. (from the US Plus/4 PRG, page 315)
CHAR also locates the text cursor, and does so on both the text and graphic screens. CHAR uses standard text coordinates (0-39 and 0-24). However, if you use CHAR in split screen mode, the text will be printed on the graphic screen, even if the graphic area is covered by the text area (the 5 lines below the graphic area).
