using the oop method
try somthing like this:
#--- code
use CGI;
use strict;
my $q = new CGI;
# pass your info like the script name and params to the script like
my $String = "/path/url.pl?H_String";
print $q->header , $q->start_html ;
print $q->p(<a href="$String">I'm the generated link </a>) ;
print $q->end_html ;
#-- end code
might need an extra set of quoats around the <a> tag , havn't tested so
don't
know.
you could also do it several other ways , hell it's perl :)
hope this helps ya .

****************************************************************************
Perl'ers,
I tried this solution and it is not working. There are no errors but the
output is not displaying the links for every $_ which is H02000 for
example.
I do not understand what "/path/url.pl?H_String"; is.
what is the ? before H_string for and why
understand that the H_string will be generated from a system command for
every $_
and it looks like
sf.H02047 capacty: 189.1G space: 117.7G
Here is my code snippet
sub viewhrtlab
{
open (ARC, "archiver -v |") or error();
foreach (<ARC>)
{
print "<H3>";
if (/(?i)fs_heartlab\.1/ ..
/(?i)fs_lanv1.1/)
{
s<fs_lanv1.1><>;
$flag=1;
if ($flag==1)
{
if (/(?i)total
space available:/)
{
print
"<p><b><font color=#0000CC><u>$_";
}
else {
print
"<p><A HREF=$_></p></b></font></u></A>";
#print
"<p></b></font></u>$_";
}
}
