newby question determining name of an array at run-time

[Alfonso]

(Sorry for not finding a better title to my question. I'm not shure if
this has something to do with metaprogramming... I have hear about that,
but never had time to learn about it, so I don't know what is
metaprogramming exactly)

Is there a way to do something like this?

arr = [ "red", "green", "yellow" ]


# the following arrays should be incremented with the loop down
@red = []
@green = []
@yellow = []

#here the loop that should increment the arrays
20.times do
arr.each { |color|
rand(60)
unless @color.include?(aleat) #this doesn't work
@color.push(aleat) # this doesn't work...
end
}
end
...
...


Thanks in advance.

Have a look at instance_variable_get in the RDocs - that'll do what you want.

Cheers,

The method instance_variable_get was exactly what I needed.

Thank you very much for your answers
