OBJECTIVE To become familiar with the loop and compare instructions. After finishing this experiment, you should be able to do the following: 1. Use compare instructions, 2. Construct simple loops, 3. Write small assembly programs with user interface. LABORATORY 1. Use any text editor you are familiar with to create an. ASM file (lab4.asm). 2. Write a program that reads a string from keyboard. 3. The program should count the number of upper case characters, lower case characters, numbers and symbols in the data and display those numbers on the screen. 4. Create an executable file lab4.exe using assembler and linker. 5. The program should work as follows: lau sing his Pem 4 computer s to fat to na C:> lab4.exe prog t Contains: 5 capital letter(s) Contains: 39 lower case letter(s) Contains 1 digit(s) Contains: 16 other character(s) OBJECTIVE To become familiar with the loop and compare instructions.
