Hi,

I am new to Ruby(v 1.8.6),  
I will like to know if is possible to  
use multiple lines on a block for the each\_byte method on strings.

Something like:

coset=9  
i=0

message =  
“adsfasdfakjhkjhowerjkbvmzbcnvkfhoeiwrukfhzadsfhhfalkhweryiuwyoyqbvbv”

message.each\_byte do |letter|  
i=+1  
if i == coset  
puts  
else  
print letter  
end  
end  
this code will yield : syntax error, unexpected $end, expecting kEND  
Any explanation will be appreciated.  
Thanks  
-L

i=0  
puts i # =\> 0  
i+=1  
puts i # =\> 1  
i+=1  
puts i # =\> 2  
i=+1  
puts i # =\> 1  
i=+5  
puts i # =\> 5

i will always be 1 (ie i = +1)  
you want i+=1

If I run your code here, it runs without error (well, i will always be  
1, so  
the if-part will never execute, but the program finishes successfully  
without  
error message).

$end means the end of file  
kEND means the ‘end’ keyword

So the error message is saying: “Hey, I ran out of code when I still  
expected to see an ‘end’ to close a block (‘do’), ‘if’, ‘for’,  
‘while’, etc.”
