ASPL 1> ks x1 y1 x2 y2 x3 y3
set the ks vector to shorten the displayed data
ASPL 2> P12_90 = ggRPI2Pov(N,90,glb1,P1,glb2,P2,nmfl,P12_90)
get random polygons in two 2D planes also generate named data in ~tmp
ASPL 3> split P12_90 into P1 P2
split the variable P12_90 for the two planes
ASPL 4> f& P1 P2
intersect the two planes
ASPL 5> f\ P1 P2
get the difference between 1st plane and the 2nd plane, the result is pushed on the stack
ASPL 6> f\ P2 P1
get the difference between 2nd plane and the 1st plane, the result is pushed on the stack
ASPL 7> ans
print the answer stack
ASPL 8> pop P2_1
pop the stack result into variable P2_1 as the difference f\ P2 P1
ASPL 9> pop P1_2
pop the stack result into variable P1_2 as the difference f\ P1 P2
ASPL 10> pop P12
pop the stack result into variable P12 as the intersection f& P1 P2
ASPL 11> ans
print the answer stack
ASPL 12> v
print the symbol table
ASPL 13> dumpgad P12
dump GADg of P12 write it to a file in ~tmp directory
ASPL 13> dumpgad P1_2
dump GADg of P1_2 write it to a file in ~tmp directory
ASPL 13> dumpgad P2_1
dump GADg of P2_1 write it to a file in ~tmp directory
ASPL 13> dumpgad P12_90
dump GADg of P12_90 write it to a file in ~tmp directory
ASPL 14> bye
save and quit.. sweet!
