        !            15:      _I-_x_r_e_f provides a cross-reference facility for Icon pro-
        !            16:      grams. It lists the occurrences of each variable by line
        !            17:      number. Variables are listed by procedure or separately as
        !            18:      globals.  The options specify the formatting of the output
        !            19:      and whether or not to cross-reference quoted strings and
        !            20:      non-alphanumerics. Variables that are followed by a left
        !            21:      parenthesis are listed with an asterisk following the name.
        !            22:      If a file is not specified, then standard input is cross-
        !            23:      referenced.
        !            24: 
        !            25:      The following options change the format defaults. They may
        !            26:      appear in any order:
        !            27: 
        !            28:      ----cccc _n   The column width per line number. The default is 4
        !            29:             columns wide.
        !            30: 
        !            31:      ----llll _n   The starting column (i.e. left margin) of the line
        !            32:             numbers.  The default is column 40.
        !            33: 
        !            34:      ----wwww _n   The column width of the whole output line. The
        !            35:             default is 80 columns wide.
        !            36: 
        !            37:      Normally only alphanumerics are cross-referenced. These
