Very strange Clipper effect... (solution)

Very strange Clipper effect... (solution)

Post by Wolfram Schlickenried » Sat, 18 Jul 1992 21:02:45



        I had a problem with a few simple lines of code: the code
        below produced a white box in the first line of the screen --
        in addition to the one a position 10, 10, as it is supposed to
        behave...

        Many people pointed out that I had forgotten to issue the READ
        statement, but in fact I did, I just forgot to include the
        line in the original article... Sorry...

        Ths solution was to issue a "set scoreboard off" command

        Thanks to everyone who responded. Regards...

1. Very strange Clipper effect...

       Hi...

       To make a long story short, I have not yet managed to find out,
       why the following four very simple lines of code don't produce
       the desired effect -- namely to read something to the variable
       named "name" without any additional white boxes appearing on
       the screen...:

----------------------------------------------------------------------
       cls
       name := SPACE (10)

       setcolor ("w/w")    <- This is the line producing a white box
                              in the first line of the screen
       ? "name = " + name
----------------------------------------------------------------------

        Anyone else observed this? Any suggestions, where it might
        come from?

        Bewildered...
