Chapter12Program Flow Constructs¶
The assembly language we have studied thus far is executed in sequence. In this chapter we will learn how to organize assembly language instructions to implement the other two required program flow constructs—repetition and binary decision.
Text string manipulations provide many examples of using program flow constructs, so we will use them to illustrate many of the concepts. Almost any program displays many text string messages on the screen, which are simply arrays of characters.
