Lesson Introduction

This section provides "walk-through" lessons on the use of IFs. If possible, print the topic/lesson of interest to you and then follow it through carefully. It is usually best to proceed through the lessons in sequence. Take a look at the Purposes of IFs to learn about basic elements and functionalities of the IFs system, before you start these lessons.

Begin each lesson looking at the Main Menu of IFs, which you reach after you start IFs.

• How do I display information that comes with IFs and from already pe-packaged and pre-run scenarios? Lesson 1.

• How do I display and/or analyze data from the historic data set that comes with IFs? Lesson 3.
