This rule applies whenever an ``++IF++`` statement is followed by one or more ``++ELSE IF++`` statements; the final ``++ELSE IF++`` 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 ``++ELSE++`` clause in a ``++CASE++`` statement.

IF @x = 1
|
|
PRINT 'A'
|
|
ELSE IF @x = 2
|
|
PRINT 'B'
|
|
ELSE IF @x = 3
|
|
PRINT 'C'
|
|
-- Noncompliant; final ELSE is missing
