Programming Without Coding Technology (PWCT) - Functions and Procedures
0 likes167 views
This document discusses creating functions and procedures in a programming application. It provides step-by-step instructions for adding components to a steps tree to define a procedure called "myproc", define a function called "myfunc" that takes a parameter, call the procedure and function, and print output to the console. The final steps tree shows the flow of calling the procedure, calling the function with a parameter, and printing output.
