This rule applies whenever an ``++If++`` statement is followed by one or more ``++ElseIf++`` statements; the final ``++ElseIf++`` should be followed by an ``++Else++`` statement.
|
|
|
|
The requirement for a final ``++Else++`` statement is defensive programming.
|
|
The ``++Else++`` statement should either take appropriate action or contain a suitable comment as to why no action is taken. This is consistent with the requirement to have a final ``++Case Else++`` clause in a ``++Select Case++`` statement.
