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 ``++OTHERS++`` clause in a ``++CASE++``
|
|
|
|
statement.
