Modify sub to exit if password is incorrect

[Max]

How could the sub below be re-expressed the other way around, ie
check the password, then exit sub immediately (with the error msg) if
password is incorrect?

Sub TestRest()
Sheet8.Select
Dim ThePassWord As String
Dim t As String
t = "What's the password"
ThePassWord = InputBox(prompt:=t)
If UCase(ThePassWord) = "BATTLEFIELD" Then
Range("D10").Value = Range("G15").Value
Else
MsgBox "That is incorrect."
End If
End Sub

Try this idea

Sub passwordcheck()
pw = "yourpasswordhere"
ans = InputBox("Enter password")
If ans <> pw Then
MsgBox "Wrong PW"
Exit Sub
Else
With Sheets("sheet7")
..Unprotect Password:=pw
..Range("f13") = "hello there"
..Protect Password:=pw
End With
End If
End Sub

Many thanks, Don. Your idea was illustrative, and I was able to apply it
successfully.
