Well, shucks! You're apparently talking about something internal now,
not labeling on a product or package, catalog description,
advertisement, or contract. In otherwords, this is a coded list. If you
provide the safeguards to state that all dimensional data is in
millimeters, in order to remind your people, you could even drop the
units if you wanted, or do as you proposed to keep the dimensions
distinct from temperature, current, power data, etc. The latter point is
important as pointed out recently when Lockheed-Martin sent data in ifp
units to JPL (?) who thought it was in SI units. A file of nothing but
numbers looks pretty much like vanilla.
Since this is an internal, coded document, I see no problem, Jim. OTOH,
if this is what you present to your public, expecting them to make heads
or tails of your 40-character product descriptions, I suspect that
investing in more robust file architecture might be well worth the
dollar spent. You could even keep your own records in that abbreviated,
coded form and have a "catalog generator" program translate it into
proper and readable data for public consumption. Even I could write a
simple record-at-a-time program to reformat the data, so that's
obviously not too hard.
Jim
