Hey all.
I seem to get this error whenever I run my program.

What does this mean? Here is my code:

Suggestions? Any?

English is like a pseudo-random number generator - there are a
bajillion rules to it, but nobody cares.

Hey all.

What does this mean? Here is my code:

snip

@names { |f| lines =
f.readlines ### LINE 58
lines.puts unless $. == selected.chomp
}
### LINE 60

Untested, but shouldn't this be

@names.each{ |f| lines =
f.readlines ### LINE 58
lines.puts unless $. == selected.chomp
}

It's Ruby's way of telling you that your code doesn't make sense.

Basically, you are defining a block for an instance variable here,
but only methods can take blocks in Ruby. I assume you meant to call
some iterator and forgot to include the method name.

Hope that helps.

I was trying this:
@names = open('.names.txt', 'w+')
in initialize, and then write to that file later on. Is there a
better way to do this?

Hope that helps. It did!

This is fine and in that case you don't need the block at all. You =20
can just write to the file with:

@names.puts "=85"
