I want to pack an array such as [1,2,3,4]
to "1234", instead of \001\002\003\004, how to do that?

% irb
>> x = [1,2,3,4]
=> [1, 2, 3, 4]
>> x.join('')
=> "1234"
>>

I just tried this in irb:

irb(main):112:0> [1,2,3,4].to_s
=> "1234"

careful w that.

C:\family\ruby>ruby -e "puts RUBY_VERSION;puts [1,2,3,4].to_s"
1.8.6
1234

C:\ruby1.9\bin>ruby -e "puts RUBY_VERSION;puts [1,2,3,4].to_s"
1.9.0
[1, 2, 3, 4]

kind regards -botp
