''This style of code is rarely used.''
=== Return / Exit Sub ===
This shows the classical and modern syntax for exiting a sub routine early.
Sub Foo1()
If Not WorkNeeded() Then Exit Sub
DoWork()
End Sub
Sub Foo2()
If Not WorkNeeded() Then Return
DoWork()
End Sub
=== Return value / Exit Function ===
This shows the classical and modern syntax for exiting a function early. There is an implied variable with the same name as the function. This variable is write-only.
Function Foo3()
Foo3 = CalculateValue()
If Not MoreWorkNeeded() Then Exit Function
Foo3 = CalculateAnotherValue()
End Function
Function Foo4()
Dim result = CalculateValue()
If Not MoreWorkNeeded() Then Return result
Return CalculateAnotherValue()
End Function
