Info

xxiii examples that can be copied directly to your programs. This option is not available to users of the Bronze edition. • FORMS – this section describes how to use the FORMS program to create windows and objects and automatically generate code. This option is not available to users of the Bronze edition. Note: The editor automatically reads all TXT files that reside in the TBhelp folder and creates the CONTENTS list from these files. To add another help file to this list, all you have to do is drop the file into the TBhelp folder and the editor will do the rest. If you wish to add more help files you may use Notepad or the TB Editor to create additional menu items.
23 CHAPTER CHAPTER 4 Writing and Running Your First Program Start True BASIC, if you haven’t already, as described in the preceding chapter. This time, instead of using an existing program, you’ll create your own in the editing window. If you’ve just started True BASIC BRONZE Edition and chosen "New", you’ll have a blank editing window called “Untitled 1” because you haven’t yet named your program. If you’ve been running an existing program, choose New in the File menu to get a blank window which is automatically named “Untitled #”. Creating a Program Suppose you’ve driven 420 miles on 14.3 gallons of gas. To compute your gas mileage, you would divide 420 by 14.3. You can write a program to do this for you. Type the following into the editing window. Press the Return key at the end of each line. LET miles = 420 LET gallons = 14.3 PRINT miles, gallons, miles/gallons END
