Print (totalPointsHi totalPointsLo) for driver X as a four-digit number, followed by a space. The first two digits are printed as spaces if the high byte is zero, and the third digit is printed as a space if applicable.
Print a specific driver's accumulated points as a four-digit number
Entry point Print4DigitBCD+3 in subroutine Print4DigitBCD (category: Text)
Do not print the first two digits (i.e. omit printing A)
Print the specified number of spaces
High byte of total accumulated points for each driver
