@SELECT

@SELECT[filename,top,left,bottom,right,title[,1]]:  Pops up a selection 
window with the lines from the specified file, allowing you to display 
menus or other selection lists from within a batch file.  You can move 
through the selection window with standard popup window navigation 
keystrokes, including character matching.  @SELECT returns the text of the 
line the scrollbar is on if you press Enter, or an empty string if you 
press Esc.  The filename must be in quotes if it contains whitespace or 
special characters.  The file size is limited only by available memory. 
 To select from lines passed through input redirection or a pipe, use CON 
as the filename.  If you use the optional 1 argument after the window 
title, the list will be sorted alphabetically.
