David T's reply actually came hours after I sent my post, but there
was a substantial lag in the distribution.  Apparently this list is
moderated.

The real problem here is the inability of GC to handle non-ISO
currencies.  There's no reason users should not be able to add a
non-ISO currency.  It's a silly limitation that reduces the capability
of the tool.  E.g., it would be useful for a user to be able to define
a "Skymiles" currency for a particular type of air miles.

Just because ISO is calling two commodities with differing properties
the same currency, doesn't mean you have to consider it a singular
currency in your application.  Handling currency changes just so you
could use the same currency name would be over-engineering.  There's
nothing wrong with over-engineering, but it would be more practical
for GC to have one currency for the obsolete national currency, and
another currency for the modern currency.

I checked on Japanese yen, and GC does in fact handle yen correctly
(as whole numbers).  So if the OP is certain to never need to use yen,
he could lie to GC, and use yen to represent the accounts of his new
whole number currency, and let the ISO version of his national
currency continue to represent the obsolete currency.

Or better yet, use an obscure currency instead of yen.  These are the
currencies that use whole numbers:

Some of those are obsolete, which is ideal for the OP to hijack.
E.g. the Italian lira.
