Lhatom-var

Make-lhatom-var

Basic constructor macro for lhatom-var structures.

Syntax

(make-lhatom-var [:name <name>] 
                 [:rsh <rsh>])

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

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