Green  Flag  IF…THEN…ELSE  Block  The  IF…THEN  statement  does  not  provide  an  alternative  for  the  program  to  follow  if  the  condition  is  false.  The  IF…THEN…ELSE  statement  allows  the  code  to  branch  in  one  of  two  ways,  as  shown  in  Figure  5-6.  if  else  then  Condition  to  test  is  inserted  here  Code  to  execute  when  the  condition  is  true  is  inserted  here  Code  to  execute  when  the  condition  is  false  is  inserted  here  Goodheart-Willcox  Publisher  Figure  5-6.
