Hi, when testing the properties of Rebol strings I came to: >> a: skip [1 2 3 4 5 6] 3 == [4 5 6] >> index? a == 4 >> b: head a == [1 2 3 4 5 6] >> remove back tail b == [] >> b == [1 2 3 4 5] >> remove back tail b == [] >> b == [1 2 3 4] >> remove back tail b == [] >> b == [1 2 3] >> remove back tail b == [] >> b == [1 2] >> index? a ** Script Error: Out of range or past end. ** Where: index? a which seems to be in accordance with the model proposed...
