Program code to be executed if the corresponding condition-n is True.
Program code to be executed if the corresponding condition or condition-n is False.
Executes a statement or block of statements based on the Boolean (True or False) value of an expression.
If condition is True, the statements following the If are executed.
If condition is False and no Else or ElseIf statement is present, execution continues with the corresponding End If statement. If condition is False and ElseIf statements are present, the condition of the next ElseIf is tested. If condition is False, and an Else is present, the statements following the Else are executed.
In the block form, each If statement must have a corresponding End If statement. ElseIf statements don't have their own End If. For example:
If condition Then statements ElseIf condition Then statements End If
ElseIf and Else are optional, and any number of ElseIf and Else statements ...
