@siz: indeed! In fact all old accountant machines and many old O.S. worked in BCD.
@Bionic: with BCD you have 2 digit in 1 byte. The convertion to string is easy (BCD nibble + $30) and the convertion to screencodes is the same.
With BCD, programmer had not to care about the skipping $A...$F, carry was automatic and overflow too. So called 'Registers' were clusters of 8 BCD bytes then achieving values from -999.999.999.999.999 to +-999.999.999.999.999 not bad!!! Oops this remember me something (BalSys)
