Subject: Re: Beginner's question: assigning same value to many variables

No, that doesn't work. We want each variable initialized to a  
_different_ empty string.

a, b, c, d = Array.new(4) { '' }
p [a, b, c, d].collect {|i| i.object_id} #=> [74020, 74010, 74000,  
73990]

a, b, c, d = Array.new(4,'')
p [a, b, c, d].collect {|i| i.object_id} #=> [73920, 73920, 73920,  
73920]

a, b, c, d = [''] * 4
p [a, b, c, d].collect {|i| i.object_id} #=> [73820, 73820, 73820,  
73820]

Regards, Morton
