I need help.   I made these two routines:

include svga.e
include graphics.e

atom destination, what, howmuch, junk
destination = allocate (10000)
what = 4
howmuch = 10000
junk = graphics_mode (261)

procedure putregion(atom x, atom y,  atom xwidth, atom ywidth, atom location)

     object data

    -- read & write picture data 1 line at a time
    for counter=0  to xwidth * ywidth by xwidth do
        data = peek ({location+counter,xwidth})
        pixel (data, {x,y})
    end for

end procedure

 procedure test_putregion(atom destination, atom what, atom howmuch)
    atom x, y, xwidth, ywidth
    mem_set (destination, what, howmuch)
    x=10
    y=10
    xwidth=100
    ywidth=100
    putregion(x,y,xwidth, ywidth, destination)

end procedure

...and there are other things so I don't think i missed anything obvious
When I run it I get an error that says bytes_per_line has no value in Pete's
svga.e
I'm inclined to think that my program is at fault.  Anyway, this is part of
ex.err:

xwidth = 100'd'
 ywidth = 100'd'

in both procedures putregion and test_putregion!
I assigned them 100.  Could someone tell me what is wrong?

TIA,
