This document provides steps for creating a program to read a file in PWCT 1.9 Art Documentation. It explains how to add components to build the logic, including opening a file, assigning a variable, reading from the file, printing to the console, and waiting. Screenshots illustrate selecting components and setting properties to open and read a test file, then print and pause the output. The final steps tree diagram shows the completed program logic and flow.
