Q-char

Make-q-char

Basic constructor macro for q-char structures.

Syntax

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

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

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