help with an Scheme function

[stebi@luxwg.de (Stebi)]

Hi there

I need a function that does the following:

(find-list '(1 2 3) '(1 2 3 4 5 1 2 3 4 5 1 2 99))
=> (0 5)


it is a function that searches the position of the sublist in this
case '(1 2 3) in the entire list ???

I'm trying to write that function now for several hours, but I don't
get a result

so can please somebody help me????


thx a lot :)
