Rule description

• Loops with at most one iteration should be refactored

Non-compliant Code Example

function integer TestFunctionCall (integer cnt)

integer A = 1, B = cnt

DO WHILE A <= 15 //Non compliant code (Only one iteration will take place because of EXIT)
      A = (A + 1) * B;
      EXIT;
LOOP

return A

end function

Compliant Code Example

function integer TestFunctionCall (integer cnt)

integer A = 1, B = cnt

DO WHILE A <= 15 //Compliant code
      A = (A + 1) * B;
         IF counter > 10 THEN
		    EXIT;
	    ELSE
		    A = B;
	    END IF;
LOOP

return A

end function

function void TestFunctionCall ()
do while IsValid (lpo_parent) //Compliant code
	if lpo_parent.TypeOf() <> window! then
		lpo_parent = lpo_parent.GetParent()
	else
		exit
	end if
loop
end function
