How to display line by line elements with one extension in a folder into variables?

Question

cmd/bat

There is a bat file and a folder
You need to do something like this:
In the folder: abc.bat, habr.bat, file, notdisplay.vbs
Display only batch files (abc.bat, habr.bat) in variables,
Delete 4 letters from the back (.bat)

and preferably, when adding files, variables of the type were created:
% punkt1%
% punkt2%
% punkt3%
, etc.

And later use it in cmdmenusel

Is this possible?
If so, how?
