append .cvs behind an array value

[Martin Sharon]

I want to add ".cvs" at the end of a name,and use the following
sentenses:


namelist.each do |name|
name = name +'.cvs'
end

but error message is :

test2.rb:43:in `+': can't convert String into Array (TypeError)
from test2.rb:43
from test2.rb:39:in `each'
from test2.rb:39

What's wrong with it? how to fix it?

thanks!

If your objects in namelist are enumerable objects, then you must
further take it apart.

It's an arry object.

..and how do you step through an array?

arrayname.each do |name|
puts name
