   Syntax       %LIST% {&label& {%TO% &filename&}}

   Where        &label& may be a label with or without the subscripts.
                If &label& is a tensor and the subscripts are omitted
                then the whole tensor is listed.

                &filename& is an alphanumeric string.  It may contain no
                more than eight characters.

   Note         When data is listed to a file, the extension 'TXT' is
                appended to the filename.  The text listed to this file
                is suitable for importation into many word processing
                programs.

   þLIST A                              ITERATE I FROM -N TO N ;
