PLEASE USE THE CODE PROVIDED IN THE ATTACHMENT AS A TEMPLATE. 

I have already completed the first part of this assignment and just need help with the second part which is putting the numbers in groups and separating them by a user specified character. Again, please use the code attached as a template and comment work. Thank you.

Modify the code so that FORMAT_NUMBER has additional capabilities.

1) Add a character that is used to LEFT PAD the output - currently this occurs in FORMAT_NUMBER and is hard coded as a SPACE (' ') character.  You must modify it so the character (FILLCHAR) is passed into the proc as a stack parameter (along with the other existing stack parameters).  You will need to modify FORMAT_NUMBER itself, obviously.  You will also modify the several MACROs so that they pass the appropriate padding character parameter to FORMAT_NUMBER.  You *can* hardcode the character in each macro ('0' for BIN and HEX, SPACE ' ' for decimal) - but you can probably see how to modify the macros themselves so the character is passed INTO THE MACRO in the PRINT_ROW proc.

2) Continue modifying the code.  Add a GROUP_SIZE mechanism to FORMAT_NUMBER, with a GROUP_CHAR character that separates digit groups.

Example:    GROUP_SIZE = 4,  GROUP_CHAR = '_'  (as would be used for binary)

                   0000_0000_0110_1011  - with above values, the binary output is groups of 4 digits, see?

Again, these must be parameters (on the stack) to FORMAT_NUMBER, ditto the Macro changes.
