    Summary: Print an 8-bit number, left-padded to 3 digits, and optional point
    Context: See this subroutine in context in the source code

             * TT25 calls via pr2+2


 Print the 8-bit number in X to 3 digits, left-padding with spaces for numbers
 with fewer than 3 digits (so numbers < 100 are right-aligned). Optionally
 include a decimal point.


 Arguments:

   X                    The number to print

   C flag               If set, include a decimal point


 Other entry points:

   pr2+2                Print the 8-bit number in X to the number of digits in A

 LDA #3                 ; Set A to the number of digits (3)

 LDY #0                 ; Zero the Y register, so we can fall through into TT11
                        ; to print the 16-bit number (Y X) to 3 digits, which
                        ; effectively prints X to 3 digits as the high byte is
                        ; zero
