WriteBinB PROC    (Not covered in the 4th edition)

   Writes an unsigned 8, 16, or 32-bit number to standard output in ASCII binary format.
   EBX must contain the TYPE of the number to write (1 for BYTE, 2 for WORD, or 4 for DWORD)
   The binary bits are displayed in groups of 4 for easy reading.

Call args:  AL, AX, or EAX = the number to write.
            EBX = 1 to write AL as 8 binary digits,
            EBX = 2 to write AX as 16 binary digits,
            EBX = 4 to write EAX as 32 binary digits.

Return arg: None

Example:

      .data
      bValue BYTE 'A'

      .code
      mov  eax,bValue
      mov  ebx,TYPE bValue
      call WriteBinB

Output:  0100 0001
