BCD Encoding?

[Randy Spangler]

Microsoft Macro Assembler 5.2 manual gives the following:

Packed BCD numbers are stored 2 digits to a byte, with one digit in the 
lower 4 bits and one in the upper 4 bits

Unpacked BCD numbers are stored one digit to a byte, in the last 4 bits.
The sign is in the leftmost bit (0 is +, 1 is -).
