Chapter 8
Data and control structures
Abstract
The chapter begins with introduction to some assembly language concepts and to program structures, both necessary for implementing code and structuring it correctly. The section on data structures shows the programmer the standard alphanumeric table, ASCII. Under character operations, two detailed programs are presented. One program counts the number of characters in a string. The second does a pattern matching scheme to determine whether two strings are the same or different. Finally, the four control structures (Function, Sequence, Alternation, and Repetition) presented in Chapter 7 are reviewed with implementation code for each structure.
