[REBOL] How to load func defs at start-up

[tim]

Hi:
    How may I load function definitions at startup?
As an experiment, I added the following function def
to both user.r and rebol.r:
import: func[{"do" a file (IMPORT function def}f[string!]]
[do make file! f]

However, upon starting rebol, rebol does not recognize
it.

I note also, that set-user is not recognized.

Just curious...
TIA
Tim
