If BooleanExpr Then
Block1
Else
Block2
EndIf
If BooleanExpr evaluates to true, executes
Block1 and then skips Block2.
If BooleanExpr evaluates to false, skips
Block1 but executes Block2.
Block1 and Block2 can be a single
statement.
If BooleanExpr1 Then
Block1
ElseIf BooleanExpr2 Then
Block2
⋮
ElseIf BooleanExprN Then
BlockN
EndIf
Allows for branching. If BooleanExpr1
evaluates to true, executes Block1. If
BooleanExpr1 evaluates to false, evaluates
BooleanExpr2, and so on.
