I started to reply to this that one could just Query(EOLType) and use the 
return value in a clone of the Semware-supplied showcurr.s macro that puts 
the hex value of the current character on the status line at the right 
end.  But when I tried it, if an EolType is not specified, Query(EOLType) 
just returns 0 for "As Loaded" without telling you what EOL type
the loaded 
file is actually using in the disk file.  I don't find anything in the 
catalog of editor variables that would do that?  But clearly it has to be 
saved in some variable when the file is loaded so that it can be used when 
the file is saved.

Here's a quick macro that came from James C. Sewall in 1996 for TSE for 
DOS, to pop up a menu to set the EOLType.  It should run unmodified in TSE 
4, I think. (This setting can also be made from the TSE Options menu, a 
couple of levels down, of course.)

       /*********************************************************
         EolMenu will present the user with a selectable menu
         of choices for a current End Of Line mode.  This is
         useful if you edit Dos and Unix style files.
       *********************************************************/
menu EolMenu()
     Title = "Select Mode:"
     "&Unix Style [LF]"
     "&Dos Style  [CR/LF]"
     "&Mac Style  [CR]"
end

proc Main()
     integer rc

     GotoXY(5,10)
     rc = EolMenu()

     case rc
       when 1
         Message("Unix Style Selected [LF]")
         Set(EOLType,2)
       when 2
         Message("Dos Style Selected [CR/LF]")
         Set(EOLType,3)
       when 3
         Message("Mac Style Selected [CR]")
         Set(EOLType,1)
       otherwise
         Message("Aborted EOL change.")
     endcase
end  // Main()
