there is a problem here. consider..

irb(main):003:0> puts [10,1]
10
1
=> nil
irb(main):004:0> puts [10,1].to_s
101
=> nil

i think you wanted the latter, so

fileOut.puts(histHash[i].to_s)

should do.

some tips:

1 try unit test
2 yaml
3 marshal

Peña,

Yes, that was what I needed. And I will look into yaml and marshal.
Uh, how ro I find documentation about unit test? In any case, thank you
very much.
