Else Following If and Then , executes a group of commands if condition is false
For( variable , begin , end
ã , step ä )
Starting at begin, repeats a group of commands by an optional real step
until variable > end; default step is 1
End Identifies the end of a group of program commands; For( , While ,
Repeat , and Else groups must end with End ; Then groups without an
associated Else instruction also must end with End
