Hello,

First, let me disclaim:  I know absolutely nothing about CGIDEV2. I'm only
familiar with "normal" CGI programming (i.e. without a toolkit)  Some day
I'm going to learn CGIDEV2 (someday, someday...)

However, what I do is use the following subprocedure to convert the
special characters into HTML-friendly variants:

      *+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
      * FixChar():  This trims trailing blanks from a source record,
      *             adds a newline and converts
      *                  & to &amp;
      *                  < to &lt;
      *                  > to &gt;
      *+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
     P FixChars        B
     D FixChars        PI
     D   SrcDta                    1024A   const varying options(*varsize)
     D   Output                    4096A   varying
     D   html_format                  1N   const
     D   HeavyTags                    1N   const

     D Len             s             10I 0
     D x               s             10I 0
     D Char            s              1A

      /free
        Len = %len(%trimr(SrcDta));
        %len(Output) = 0;

        for x = 1 to Len;

           Char = %subst(SrcDta: x: 1);

              if (html_format);
                 if (Char = '<');
                    Output += '&lt;';
                 elseif (Char = '>');
                    Output += '&gt;';
                 elseif (Char = '&');
                    Output += '&amp;';
                 else;
                    Output += Char;
                 endif;
              else;
                 Output += Char;
              endif;

        endfor;

        if (html_format and HeavyTags);
          Output += '<br>';
        endif;

        Output += x'0d25';

      /end-free
     P                 E

I imagine that if you created a CGIDEV2 thinngy, you wouldn't need to add
the <BR> or whatever to the end of the data.  You'd want your template to
use <PRE> and </PRE> most likely instead.

Then, of course, I'd read the file in my RPG program and run line of input
through the above subprocedure... then write it out to stdout (or in your
case, to the CGIDEV2 template.)
