	Set up
		: Get your stuff working under subversion
		: Go to 310/cs310gpXX/1
		: svn export http://unbox.org/wisp/var/timm/10/310/src/gawk/1/b
		: svn add b
		: svn commit -m "b ready to go"
		:
For each of the following questions, add lines like this to "run"
	printf "\n===== 1/b/q1 ========================\n\n"
	cat myCodeThatAnswersThisQuestion.awk
	execute
		: where "execute" is the "test" command shown below.

Q1
	Write
		: Write an awk program that reads every line, and outputs that line, with
		: its line number. 
		: Use that file to write out this file.
	Test
		: gawk -f linenum.awk linenum.awk
	Hint 
		: The curent line number is stored in FNR

Q2
	Write
		: Write an awk loop that reads every line of input into an array.
		: Then print that array in reverse order.
	Test
		: gawk -f reverse.awk linenum.awk
	Hint
		: The current line number is the variable FNR.
		: The last thing Awk does is to run the code in 'END { codeToRunLast }'
		: Line 96 of stork.awk shows a for loop

Q3	
	Write
		: Write an awk program that prints out (one per line) all the 
		: left-hand-side "variables" (i.e.  : non-terminals").
		: Test that on scifi.rules
	Test
		: gawk -f lhs.awk scifi.rules
	Hint
		: $1
	
Q4	
	Write
		: Write an awk program that prints out (one per line) all the 
		: right-hand-side "variables" (i.e.  : non-terminals").
		: Test that on scifi.rules
	Test
		: gawk -f rhs.awk scifi.rules
	Hint 
		: for(i=1;i<=NF;i++) print "the " i "-th field is " $i

Q5
	Write
		: Write an awk program that prints out (one per line) all the 
		: right-hand-side "variables" not found on the left hand side.
		: Test that on scifi.rules
	Test
		: gawk -f badright.awk scifi.rules
	Hint
		: combine Q3,Q4 code

Q5
	Write
		: Write an awk program that prints out (one per line) all the 
		: left "variables" that never appear on the right hand side.
	Test
		: gawk -f badleft.awk scifi.rules
	Hint
		: combine Q3,Q4 code
