Tried to do a graphic plotter. Imported a txt-file with 20 rows and 20 char 0 or x in each row. The Scratchprogram read the list and plot a dot for each char in the list. Then if you press <space> it scan the rows for x or 0 (could have been 1 or 0) and put them in a new list. Next you press <c> for a smaller copy of the image.
