i am trying to loop and increment the value in DL but when i run it .it does not show anyting or rather it shows the 'space' character only .i wanted to do this on DEBUG environment so please don't tell me to use TASM xD

Solution

  • You should change your loop instruction, because right now it resets dl with 20h, that's why it prints only the space character. Try looping directly on the int 21h instruction.
