     _I-_x_r_e_f provides a cross-reference facility for Icon pro-
     grams. It lists the occurrences of each variable by line
     number. Variables are listed by procedure or separately as
     globals.  The options specify the formatting of the output
     and whether or not to cross-reference quoted strings and
     non-alphanumerics. Variables that are followed by a left
     parenthesis are listed with an asterisk following the name.
     If a file is not specified, then standard input is cross-
     referenced.

     The following options change the format defaults. They may
     appear in any order:

     ----cccc _n   The column width per line number. The default is 4
            columns wide.

     ----llll _n   The starting column (i.e. left margin) of the line
            numbers.  The default is column 40.

     ----wwww _n   The column width of the whole output line. The
            default is 80 columns wide.

     Normally only alphanumerics are cross-referenced. These
     options expand what is considered:

     ----qqqq     Include quoted strings.

     ----xxxx     Include all non-alphanumerics.

     This program assumes the subject file is a valid Icon pro-
     gram. For example, quotes are expected to be matched.
