If...Then...Else

Conditionally executes a block of statements based on the value of a Boolean expression.

Syntax

' Block form
If condition Then
    [statements]
[ElseIf condition2 Then
    [statements]]

    [statements]]
End If

If condition Then statement [Else statement]

Parameters

• condition: A Boolean expression to evaluate.
• statements: One or more statements to execute when the condition is met.

Remarks

• Multiple ElseIf branches can appear between If and Else.
• Only the first branch whose condition is True executes.
• The Else branch executes when none of the preceding conditions are True.
• In the single-line form, End If is not used and only one statement may follow Then or Else.

Dim score As Integer
score = 75

If score >= 90 Then
