Subject: [ruby-talk:6789] using join()


while I await the "Programming Ruby" book.  Can someone tell me what
I'm doing wrong here:

i = j = 2
a = join(":",i,j);
print a

undefined method `join' for #<Object:0x8106cd8> (NameError)

also, is it true that this:

s/^\s+|\s+$//   # trim whitespace

doesn't work?

when I changed it to:

 line = $_
 line.sub!(/^\s+|\s+$/ , "") # trim whitespace

it appeared to work.  Just wondering if s/// works in ruby and I'm doing it
wrong.  I also tried $_ =~ s/^\s+|\s+$//

thanks,
