How do I print a new line of text (on the monitor) over a previously printed line of text after clearing (erasing) the previous line of text. I wish to avoid overwriting (comingling) the letters of the first line with the second line. For example the desired outcome of the following would be the sole word goodbye on cursor location 0,0.

set cursor 0,0
print "hello"
set cursor 0,0
print "goodbye"
I do not want to use cls to clear the entire screen.

You could use the box command, eg.



Manually syncing the screen isn't really required for simple programs that just useing print.

Thanks for the help. The box routine works just fine.

I'll be ready for the sync later.

For accuracy, just set the ink to black(or whatever your background color is), print your comment that is already there, set the ink to white, and print your new comment.

If this is DBPro (Not sure About DBC) Then the command

SET TEXT OPAQUE will cause it to overwite what is under it and
SET TEXT TRANSPARANT (The default) will cause it to leave what is under the text in place.
