Updating The Current Graphic Window
Syntax gupdate
See Also gplot

Redraws the current graphics window. While processing a sequence of commands (such as those in a "begin/end" block), O-Matrix does not normally update the current graphics window. Adding gupdate to a sequence of commands causes O-Matrix to redraw the current graphics window in the middle of the sequence. (The current graphics window is automatically redrawn before another graphic window becomes current.)

If you enter
     for i = 1 to 5 begin
          gplot(seq(2) + i)
O-Matrix will plot five lines, with one second of delay between each line, in the Graphic 0 window.
