Untested, but should work.

 Code:

; not only good practice, but needed because you are using "C$" in a string
; to specify the admin share!
$ = SetOption('NoVarsInStrings', 'On')

If Open(1,"SymForm.txt",2) = 0

  ; send all output to this file
  $ = RedirectOutput('\\servername\sharename\filename.txt')

  $Comp = ReadLine(1)   ; read the first line
  While Not @ERROR      ; loop until error occurs (End of File)
    If $Comp            ; process if not blank

      ; This wraps the Computer name in \\ and \, removing any slashes that already exist
      $Target = '\\' + Join(Split($Comp, '\'), '', 3) + '\'

      ; this print statement is common to all processing
      $Comp Chr(9) 
      If Exist($Target + 'C$\Program Files\SymForm API\SymStoreMod.dll')
        'File Exists' ?
      Else
        'File Missing' ?
      EndIf

    EndIf
    $Comp = ReadLine(1)	; read the next line
  Loop
  Close(1)

  ; close the output redirection
  $ = RedirectOutput('')

EndIf


RedirectOutput is so much easier to use for this kind of thing. I'd also consider using WriteProfileString to record the status to an ini file.
