have an array script need some help with rotation

i have a script that will do an array, but i also need it to rotate the object 1.4 degrees at every step in the z direction.
here is the script:

for j= 0 to 6 do
(
r=4650*j
for i = 0 to 16 do
(
sail_copy = instance $boxrot
sail_copy.pos = [(r+(i*j*f)), 0, 4000+(8000 * i)]
)
)

any help would be greatly appriciated.
