I need to create the path of a directory using different atomic symbols. So in one box I have the folders an in the other one I have the files. So in one box I have "folder1/" and the in the other one "file", I need something to concatenate them to have "folder1/file" as output.
The problem is that I need to join them and using [glue] or [pack] there is always a blank space between both symbols in the result.
Is there any way to join two symbols without space between them?
Thanks in advance.
