Looping through string values from a windows command line bat file

I am trying to create a batch script for my Windows machine that loops through a list of (string/decimal) values and uses each value as a parameter inside the loop.

Below is an example of a simple for loop I would like to use to display all the different version files (from my list)

FOR ? in ('1.1','1.2','2.4','3.9') do echo V[value_from_for_loop].txt

I am having trouble in how to loop through each item and use a variable in my echo statement.
