219. The following structured English procedure is incorrect because
case (code)
Code=2 : if purchase amount >=5000
then discount=5%
Code=1 : discount=2%
Code=3 : if purchase amount >=4000
then discount =2%
else if code=4
then discount =5%
end if
None of the above codes : discount=0
end case

1. code=2 should appear after code=1
2. if statement cannot be used within a case
3. code=4 should not be used in the action for code=3
4. The statement is correct
