What is wrong with my program?

Hi..
This is my fist time, I need your help guys to figure out what is the problem with my code. My program is to show time in this format " TIME:Hours : minute : seconds : Hunderthseconds" , but , the problem is that it didn't show correct numbers, it shows me just charachers I don't understand. As far as I know function AH = 2CH INT 21H, returns ASCII code for time " CH=hour, CL = minutes, DH = seconds, DL = 5/100 seconds"
... So, could you please figure out what is wrong with this code,
Thank you very much.

interrupt 2c returns binary numbers, not ascii. You have to convert them to ascii before displaying them.
