### Compound Type Specifier Description

This denotes the set of integers that can be represented in two's-complement form in a byte of s bits. This is equivalent to `(integer lower upper)`, where lower and upper, respectively, are `-2s - 1` and `2s - 1 - 1`. The type signed-byte or the type `(signed-byte *)` is the same as the type integer.
