As a "consumer" I'm not insulted. ;-)

It doesn't sound like this will be the only version of the chip.

Right. But discounts on higher quantities.

Is this the same as: REQUIRE must be implemented with fully qualified
filepaths?

Let's see how your problem can come up.

iForth does not have REQUIRE, only (a non-standard) NEEDS.

NEEDS uses the filename to decide loading, the path is arbritrary.
(It is used to find the file, when it is there. When there is no path,
and the file is not in the current directory, the Forth path is used.
By convention, NEEDed files are in %%IFORTH%%/dfwforth/include.)

Why not simply use the entire pathname starting from root? That way, the
directory can't change.
