Question

Design and implement Pep/8 Assembly language programs for each of the following:

A program that computes the sum of three numbers (3, 4, 2) and displays the result

PEP/8 Simulator/Assembler information is available at: http://computersystemsbook.com/4th-edition/pep8/

Dr. Stan Warford's presentations on Assembly Language available via iTunes at https://itunes.apple.com/us/course/id546468937

Also be sure to review the Assembly Language program examples included in the Pep/8 "Help" menu since these will provide you great models for completing these programs.

please follow link and examples and use this assembler
