Syntaxerror with HERE document

Ruby

Why does the following statement give syntax error “undefined method
`STDOUT’”?

STDOUT <<-END
line 1
line 2
END

After all, the following works:

s=<<-END
line 1
line 2
END
STDOUT << s

Because that’s equivalent to STDOUT “bla”, not STDOUT << “bla”.
The << in your code is part of the heredoc syntax. You want
STDOUT << <<-END
line 1
line 2
END

this means:
tmp_str=“line 1\nline 2\n”;
STDOUT tmp_str;

After all, the following works:

s=<<-END
line 1
line 2
END
STDOUT << s

and this means:
tmp_str=“line 1\nline 2\n”;
STDOUT<<tmp_str;

STDOUT is a var(the std out)
“<<” is a method of STDOUT

Of course, that’s it!!! I must have been blind! Thanks a lot.
