Description
The If .. Then .. Else statements are used to conditionally execute commands based on the value of an
expression.
Consider this command:
If ('x' == 1) Then Cue 1 Go
The above example first checks the value of the variable x , and if it is equal to 1, then Cue 1 is executed.
On the other hand, if x is not equal to 1, then nothing will happen. Since no commands are present after the
“Cue 1 Go”, an EndIf is not necessary.
See the section on Expressions for more information about the kinds of expressions that can follow an If
statement.
Using Else
The Else keyword can be used to execute commands if the expression is false. Consider this example:
