Question: Maple2016, about editting strings

Hi all,
I have a question about editing strings in Maple2016.
When I make a variable "DataName" which is as below in Maple worksheet,

I want to make the variable "DataSet" whose elements are as below.

Of course I can type the elements of "DataSet", but if the number of DataName increases, it requires a lot of time to do that, so I want to make the "DataSet" by using general command so that I can obtain "DataSet" automatically.
I tried to use the command "cat", "||", "map", and so on... but I could not find how to do that.
Is there anyone who can solve this problem? Please let me know how to solve this problem. I appreciate any idea you may have.

Always thanks for the nice answer
