If it is a bug, has BASIC 6.0 addressed it? > i cant think of any place that i have seen that says that you could or should get an error 19. i also havent seen any place that says this is a bug. it has, however, been this way since at least basic 2.0, and to the best of my knowledge, it continues to be this way in basic 6.0. (i havent really check 6.0 'cause all our software already handles it...) this can be a real pain to work around, especially when you need to draw a "very long" line, and one end of the line is way of the edge of the screen. the only way to draw it is to carefully calculate where the line crosses the edge of the screen and do your own clipping. *gack*. this problem also occurs when you are doing things like SET ECHO, AREA FILL, and LABEL. these commands are much harder to work around. -wayne
