HI LOGO FANS!!!!!!!

MSWLogo has two "primitives" called: SCROLLX and SCROLLY:

to horizontalscrolling
for [x 0 10 1][scrollx :x wait 3]
for [x 10 0 -1][scrollx :x wait 3]
for [x 0 -10 -1][scrollx :x wait 3]
for [x -10 0 1][scrollx :x wait 3]
scrollx 0
verticalscrolling
end

to square :side
repeat 4 [fd :side rt 90]
horizontalscrolling
end

to verticalscrolling
for [y 0 10 1][scrolly :y wait 3]
for [y 10 0 -1][scrolly :y wait 3]
for [y 0 -10 -1][scrolly :y wait 3]
for [y -10 0 1][scrolly :y wait 3]
scrolly 0
horizontalscrolling
end

Please, type: "SQUARE 100" and see the scrolling effect.

Of course, you can to use it with the mouse wheel or other hardware
but I'm not an expert on these capabilities.

GOD BLESS YOU ALL!!!!!!!
