A. The following Pascal program asked the user to type a string and the
person typed DECEMBER.  Then it asked for another string and the person
typed FEBRUARY.  What did the program print after that?

program pres;			WRITE OUTPUT BELOW	WRITE INPUT BELOW
var				------------------	------------------
    last, next, again: string;
begin
writeln('Last month?');
readln(last);
writeln('Next one?'); 
readln(next);
again := last;
writeln(last);
writeln(next);
writeln(again); 
writeln('again'); 
end.

B. Here are some simple rules defining Pascal objects.

#1   <identifier> -> //a sequence of letters// (where // indicates italics)

#2   <string expression> -> '//any string of printable characters//'

#3   <statement> -> writeln(<string expression>)

#4   <statement> -> readln(<identifier>)

#5   <compound statement> -> begin
			     //a sequence of <statement>s each followed
					by a semicolon//
			     end

Show how these rules can be used to generate the following Pascal program
fragment.  Identify the rule used at each stage.  Continue on back as
needed.

	begin
	readln(resp);
  	writeln('Thanks for your answer.');
	end

Start with: #5	<compound statement> ->
