From this experimental module, we basically learn some very important things, such as-
- Scan data input from the user.
- Printing the input and string given by the user.
- Interrupting of the input-output by "Int 21h".
- Putting a Dollar ($) sign after every string in the data section.
- Taking AH=1 for the input, AH=2 for the output, and AH=9 for the string.
