OBJECTIVE The objective of this experiment is to learn: 1. How to write generic macros for a set of instructions performs a task that is used repeatedly. 2. How to use INT 10 and INT 21 to invoke BIOS and DOS subroutines. LABORATORY 1. Problem 1 Write a macro file that includes INT 10 and INT 21 functions as follows: a) INT 10 functions should include clear screen and set cursor position. b) INT 21 functions should include read a character and string from keyboard and print a character and string from keyboard
