Cannot define constant END

ruby-talk
1

I am trying to define a class constant named END like

class Test
HOME = 0
END = 1
end

This produces compiler error:

test.rb:3: parse error
END = 1
^

Is ‘END’ a reserved keyword in Ruby (‘end’ is, i know :slight_smile: )?

Thank you,
Gennady.

BEGIN and END are reserved Ruby keywords (like ‘if’, ‘else’ and ‘while’).
You can’t use them for variables.

You can use ‘_HOME’ and ‘_END’ if you like.

Thanks a lot !!!

I just checked with pickaxe and found that BEGIN and END declare blocks to
be executed on file load and program exit respectively. Sorry for not
checking before posting.
