mp uses odd storage techniques, etc.  I have the basic four functions (+,-,/,
*) written in C to handle any-length BCD strings (two digits/byte).  The {
routines were written for a Data Structures class (which was taught in Ada) 
and are not as optimized as they could be but they work.  If the poster
of the original request wants them, mail me!!
