Peter,

When you create a link like this, all data after the question mark can be
retrieved by the calling program as environment variable QUERYSTRING (I take
it that that is why you use data structure EnvDta).  The common way to
identify parameters to the CGI program is to use name-value pairs, e.g.:

Eval      WebOut = '<a href="http://pacnet/cgi-rpg/FD003R4?'
          + 'location=' + %trim(Location) + '&'
          + 'mfitem=' + %trim(mfitem) + '&'
          + 'mordno=' + %trim(mordno) + '">'

With location '1', mfitem '1364647' and mordno 'M111110' this would evaluate
to:
<a
href="http://pacnet/cgi-rpg/FD003R4?location=1&mfitem=1364647&mordno=M11110";
>

The CGI program can parse the query string into the individual parameters
through QzhbCGIParse or QtmhCvtDB as Bradley mentioned.
