Pnumber-dot-digit

Make-pnumber-dot-digit

Basic constructor macro for pnumber-dot-digit structures.

Syntax

(make-pnumber-dot-digit [:digit <digit>])

This is the usual way to construct pnumber-dot-digit structures. It simply conses together a structure with the specified fields.

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