I have written this a script like this:
values = [10, 20, 30].each {|value| value + (value * 10)}
puts value
In this case, I get:
undefined local variable or method `value' for main:Object (NameError)
I'm trying to see the result of the equation value + (value * 10)
What should I do?
Thanks.

Ali,
I suspect the example you're trying was actually printing out
value*s*(...s! plural NOT value)
this would then make sense as a demonstration that the 'each' loop did not
alter the array

more conclusively (using =)
array = [10,20,30]
array.each {|number| number = (number * 10)}
puts array
[10,20,30]
i.e. not [100,200,300]!
