String Variable

[Han]

Use RECT or RECT_P to erase the block you wish to "write" and then "write" using TEXTOUT (or TEXTOUT_P). As Tyann suggested, you can also use the output of the TEXTOUT command (which returns the x-coordinate of the "end" of the message string that got printed) to erase, via RECT, to the end of the screen.

I think the best way is to draw in a separate buffer (say G1) by first erasing the row with RECT_P(G1,x1,y1,x2,y2) and then using BLIT_P(G1).
