Question: How to do recursive statmants in maple


I am trying to implement a recursive algorithm for matrix inverses, its a seventh-order method

for n to 7 do
    new := (1/16*old) . (120*I + ((A . old) . (735*I + ((A . old) . (-861.*I + ((A . old) . (651*I + ((A . old) . (93*I + (A . (old(-15*I + (A . old)))))))))))));
    old := new;
end do

However I get a error informing me that this is a recursive statment. Which it is, but maple thinks this is a bad thing.

So it is clear that I am doing somthing wrong, Can anyone help me by explaining what I am doing wrong?
