Hi Scott,
Not sure I understand your question exactly.
I load this sort of stuff from my menu.MNL file or from my ACAD.LSP file.
with something like
(load "kdub_snapto.LSP")
Are you trying to Autoload it ??
with something like
(autoload "kdub_snapto.LSP" '("SAA" "kdub:snapto"))
I'm not sure if that would work ... and don't have AutoCAD handy to test
