CHAPTER 5
Impact Basic
This chapter discusses the Basic language that is used in the Basic tool in VPM and the Basic Interpreter
control in CPM. The Basic tool performs logical and mathematical calculations based on a set of user-writ-
ten statements using the Basic programming language. The program results are available to link to other
tools.
Basic Editor Window
Basic language commands are typed in the Basic editor window in the VPM Basic tool and the CPM Basic
Interpreter. As variable names are entered, variables are created as inputs in the input list. Click the Compile
button to test the validity of your Basic code. To run the tool or control, click the Run button and the calcu-
lated variable values appear in the properties tab. For more CPM details, see “Basic Interpreter” on page 4-
102. For more VPM details, see “Basic” on page 3-204.
