In the following code - I'm opening a text file and displaying it's contents - now I want to add a html checkbox to have the abaility to flag rows (how in the world can this be done

Also in perl how can a serach for a string - ideally I'd like to have a <br> after the word EDT in the txt file:

I'm not a perl guru by any means - this is likely easy
but I just don't use the language enough to know it cold:

#!/usr/bin/perl5
#
# Read in the data file
# Print out a HTML formatted lines
#

$file = 'register.txt' ;                  # Name the file
open(INFO, "<$file") ;                # Open the file
@lines = <INFO> ;                     # Read it into an array
close(INFO) ;                         # Close the file

$long_line = join("\n", @lines ) ;    # Convert array to variable
                                      # retaining end-of-line characters

@dash_sep = split ( /---------/, $long_line ) ; # split long_line at dashes

print "Content-Type: text/html\n\n";
print "<HTML> <HEAD> <TITLE> PERL output </TITLE> </HEAD>\n" ;
print "  <BODY>\n" ;

foreach $line (@dash_sep)             # assign @dash_sep to $line, one at a time
{
  $line =~ s/line of text./text fragment. /g ; # substitute text
  $line =~ s/\n//g ;                           # remove end of line characters
     
 if ($line =~ /^A third text/ )                # test for 3rd text fragment
 {
    print "    <HR> <BR> \n" ;
 }

  print "    <P> $line </P> \n" ;
}

print "  </BODY>\n</HTML>\n" ;

If the only purpose is what you stated then, display the output lines in a form, since checkboxes can only be used in a form.  So the output lines would look something like:

for (...)
  print <<EOT;
<tr><td><input type="checkbox" name="whatever"></td>
<td>$_</td>
</tr>
  }

The tabel is not required, I just think it will look neater and it will handle the lin breaks for you.

Maybe I didn't understand your snippet 100% - but when I add it into the code below - I get an internal server error:

#!/usr/bin/perl5
#
# Read in the data file
# Print out a HTML formatted lines
#

$file = 'register.txt' ;                  # Name the file
open(INFO, "<$file") ;                # Open the file
@lines = <INFO> ;                     # Read it into an array
close(INFO) ;                         # Close the file

$long_line = join("\n", @lines ) ;    # Convert array to variable
                                      # retaining end-of-line characters

@dash_sep = split ( /---------/, $long_line ) ; # split long_line at dashes

print "Content-Type: text/html\n\n";
print "<HTML> <HEAD> <TITLE> PERL output </TITLE> </HEAD>\n" ;
print "  <BODY>\n" ;

foreach $line (@dash_sep)             # assign @dash_sep to $line, one at a time
{
  $line =~ s/line of text./text fragment. /g ; # substitute text
  $line =~ s/\n//g ;                           # remove end of line characters

 if ($line =~ /^A third text/ )                # test for 3rd text fragment
 {
    print "    <HR> <BR> \n" ;
 }

  print "    <p>$line</p> \n" ;

}

{
print <<EOT;
<tr><td><input type="checkbox" name="whatever"></td>
<td>$_</td>
</tr>
 }

print "  </BODY>\n</HTML>\n" ;
