** In [[SCREEN]] 0 (text mode), the [[_HEIGHT]] function returns the number of text rows.
** In graphic modes, the number of available text rows can be calculated by dividing [[_HEIGHT]] (measured in pixels in graphic modes) by [[_FONTHEIGHT]]: '''''totalRows%'' = _HEIGHT / _FONTHEIGHT'''
:''Explanation:'' "HELLO " is printed and the semicolon stops the cursor immediately after the text. The [[CSRLIN]] variable records the current print cursor's text row in Y. The [[POS]] function records the current print cursor's text column in X. The second [[PRINT]] statement displays the comment "WORLD" on the 10th line of the screen. The last [[LOCATE]] statement restores the position of the cursor to the original line and column immediately after the first print.
