Roman numerals are typically used to demonstrate the decimal nature of a
number.  Thus the only way the "subtraction feature" is generally used is
when a 4 or 9 occurs in the decimal (Arabic notation) of a number.
            ......
I have a C program which does
just this which I'll send to anyone interested.  I've also a closely
related program which takes Roman numerals of a much more general nature
(e.g. MIM and IVX) and gives the Arabic notation version.

I would like a copy of the C program which you mentioned.
