TEXT:32,1) A program will accept data. The data will consist of numeric figures

TEXT:32,2) A program will analyze the accepted data. This step involves
TEXT:16,temporarily storing the data for both arithmetic calculations and
TEXT:16,comparison against predefined values, and then making a decision
