how to scroll big bmp's ?

[fancom]

Well,although we are going to make 3d projects i couldn't find a way to scroll a bitmap
on the screen.for example a bitmap like 32000*480*16.
cls
ink rgb(255,255,255),1
sync on
create bitmap 1,32000,480,16
for t= 0 to 1000
x=rnd(32000)
y=rnd (480)
dot x,y
next t
rem everything seems to be ok.But,
copy bitmap 1,0
rem this causes a dimension error.
how to do it?
if possible write me a simple ,large bmp scrolling program please.
Thanks a lot.
