Yes. There is probably more than 1 way to do it. We define the
"commandname" in acaddoc.lsp like this:
(defun C:LoadCityRoadTagMacro ()
(VL-VBARUN "d:\\acad\\vba\\City_Road_Tags.dvb!Main")
)
In this case, the command is now "LoadCityRoadTagMacro". In CUI, define
your button and assign the command to it as shown in the attachment.
