Hi,

I want to extend a complex, multidimensional array with (code snippet):

results.each do |result|  
result[1] \<\< [string, array]  
puts result[1]  
end  
puts results

The output of “result[1]” is correct, showing the [string, array] is  
attached.  
But putting “results” shows, that “array” is not in “results”.

Does anyone no why?

There’s no one thing that’s true. It’s all true.

I don’t understand what you are meaning.  
I have results to be extended.

You might have to post working code rather than a snippet. Putting in  
some test data seems to work fine in irb:

irb(main):001:0\> string = ‘hi’  
=\> “hi”  
irb(main):002:0\> array = [1,2,3]  
=\> [1, 2, 3]  
irb(main):003:0\> results = [[0,[]],[0,[]]]  
=\> [[0, []], [0, []]]  
irb(main):004:0\> results.each do |result|  
irb(main):005:1\* result[1] \<\< [string,array]  
irb(main):006:1\> puts result[1]  
irb(main):007:1\> end  
hi  
1  
2  
3  
hi  
1  
2  
3  
=\> [[0, [[“hi”, [1, 2, 3]]]], [0, [[“hi”, [1, 2, 3]]]]]  
irb(main):008:0\> puts results  
0  
hi  
1  
2  
3  
0  
hi  
1  
2  
3  
=\> nil
