That's not what I remember.
Yes, you was able to plot, draw and change any ASCII character straighfoward from BASIC. However, animations were limited to single NOR or OR pixels or whole characters made of 8x 8 pixels. If you wanted more elavorated animation( and they were), you needed to load your own machine code script. Management of memory screen was very tricky. Strips of 8 pixels were allocated according TV scanning and colors( atributes) were limited 8x 8 pixels cells or the size of an ASCII character. You often had to decide how to manage when two figures with different atributes were at the same cell or collided during animations. -- Julián [EMAIL PROTECTED] ================================================================To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
