the a =\<\<END\_STR  
spits out an error  
Here is what I coded with the tutorial

[code/]#p004stringusage.rb  
#defining a constant  
PI = 3.1416  
puts PI

# Defining a local variable

myString = ‘I love my city, Pune’  
puts myString  
=begin  
conversions  
.to\_i, .to\_f, .to\_s  
=end  
var1=5;  
var2=‘2’  
puts var1+var2.to\_i  
#\<\< appending to a string  
a=‘hello’  
a\<\<‘world.  
I love this world…’  
puts a  
=begin \<\< marks the start of the string literal and is followed by a  
dlimiter of your choice. The string literal then starts from the next  
new line and finishes when the delimiter is repeated again on a line  
of it own. This is know as Here document syntax.  
=end  
a = \<\<END\_STR  
#This is the string and a second line  
ENG\_STR  
puts a[/code]

btw here is the error message  
p004stringusage.rb:28: can’t find string “END\_STR” anywhere before EOF  
p004stringusage.rb:25: syntax error, unexpected $end, expecting  
tSTRING\_CONTENT  
or tSTRING\_DBEG or tSTRING\_DVAR or tSTRING\_END

Oh … it’s a tricky one. I tried it myself and the problem is caused due  
the trailing whitespace on the lines containing END\_STR. They come from  
copying the example from the web page.

Simply remove them and the example should work.
