title: Batch adding a character every x characters
body: <p>If I get my parameter with %1 and it is "Server" how can I add a + sign after every letter?
  So my result would be "S+e+r+v+e+r"?</p>
  
  <p>I think <a href="https://stackoverflow.com/questions/10021464/batch-file-to-add-characters-to-beginning-and-end-of-each-line-in-txt-file">Batch file to add characters to beginning and end of each line in txt file</a> this is a similar question but I don't know how to change the code for this purpose.</p>
  
  <p>Any help would be great!</p>
