Hello, everyone.
Subj on 1.9.3.
I tryed already:
5.times {|n| eval "house#{n} = Array.new(5)"}
Thats works but only in block scope, how can i define 5 vars in global
scope(with ability to access it out of block)?

variable names is generally a sign that either you're using foreign data
for them, or they're closely related. or both.
in the former case, doing that would be unsafe, and you should probably
use some sort of array (or a hash). the latter case ... you should also
probably do that.

> Yeah, you're right. Hash better choice for that, sorry for disturbance.
Why not an Array? You are indexing by integer anyway.
Assuming you really want five Arrays of length five each:
houses = Array.new(5) { Array.new(5) }
