UNIX for Dummies Questions & Answers

Hi!
(I guess this could of gone into the scripting forum, but Unix for Dummies seemed more appropriate. Please note that I am not in school, so Homework doesn't seem appropriate either. You guys can let me know if you think otherwise.)

I am following an exercise in a book on ksh scripting which is supposed to be about boolean operators. While I've added my own lame lines to print, and made changes mentioned below, I've otherwise copied from the book. This is the error I receive:

Code:

./boolean.ksh: line 6: syntax error at line 20: `"' unmatched

Now, I'm a total noob, and I'm probably missing something obvious, but no matter how hard I stare at lines 6 and 20, I cannot see anything wrong, especially not with the quotes. I mean, line 6 couldn't be simpler:

Code:

read age

The syntax in the book for the variables was as follows:

Code:

((age < 6))

I thought maybe that was it, because in previous examples they'd shown the syntax more like this:

Code:

(( (age < 6) ))

And they had emphasized how important white space was in ksh scripting, (although they never said exactly how). But changing it didn't make any difference. Even if it's not related to the error, I wouldn't mind hearing a comment about that.
But the fact is, I ran it in debug mode, and it never gets past my inputting the data, so the problem does seem to be line 6.

Here is the script:

Code:

#!/bin/ksh

# Please forgive my juvenile sense of humor.

print -n "Enter your age -- "
read age

if (( (age < 6) )) || (( (age > 64) ))		# || = boolean 'or'
then
	print "We give a discount to children and seniors."
	print "The price is \$100.00”
elif (( (age >= 13) && (age <= 19) ))			# && = boolean 'and'
then
	print "You are a teenager. We hate teenagers. Get lost."
elif (( (age >= 40 && age <= 45) ))
then
	print "Since you likely in a mid-life crisis, why not spend more? You will feel better about yourself.”
	print "Tickets are \$300.00.”
else
	print "Tickets are \$5.00"
fi

One of these is not like the others.

One of these just doesn't belong.

Do not type up your scripts in Microsoft Word, it will convert your ordinary quotes into "smart quotes" which aren't quotes at all as far as the shell's concerned.

Actually, I was using vim, but after I got the error the first time, I opened it in TextWrangler, and added the missing quotes. I see now that I had the prefs set to use "typographers quotes". But I guess my eyesight wasn't good enough to notice.
Ok, I changed prefs and replaced the curly quotes, and it works as expected. That was it, thanks!
