Make-register

Basic constructor macro for register structures.

Syntax

(make-register [:number <number>])

This is the usual way to construct register structures. It simply conses together a structure with the specified fields.

This macro generates a new register structure from scratch. See also change-register, which can "change" an existing structure, instead.
