H-char

Make-h-char

Basic constructor macro for h-char structures.

Syntax

(make-h-char [:code <code>])

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

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