I just show the piece of code how to write the output to a file. I expect you collate code in the existing example. OK, tried the below code.
Code:
#!/usr/bin/perl
use strict;
use warnings;
my $file1=open_file("file1.txt");
my $file2=open_file("file2.txt");
my @file1 = split(/\n{2,}/, $file1);
my @file2 = split(/\n{2,}/, $file2);
open (FOUT, ">output.txt") || die "Cannot create the output file";
for (my $i = 0; $i<=$#file1; $i++) {
print FOUT "\n----- Group ", $i+1," ------\n", "$file1[$i]\n", "$file2[$i]\n";
}
close (FOUT);
sub open_file
{
 my ($fname)=@_;
 undef $/;
 open (FIN, "<", "$fname") || die "Cannot open the input file $fname : $!";
 my $fcontent=<FIN>;
 close (FIN);
 return "$fcontent\n";
}

extract_font_range

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME

       extract_font_range - Extracts a range of characters from a font. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       FONT *extract_font_range(FONT *f, int begin, int end)

DESCRIPTION

       This  function  extracts  a  character range from a font and returns a new font that contains only the range of characters selected by this
       function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or  to  the  end  of  the
       font.  Example:

	  FONT *myfont;
	  FONT *capitals;
	  FONT *fontcopy;
	  ...
	  /* Create a font of only capital letters */
	  capitals = extract_font_range(myfont, 'A', 'Z');

	  /* Create a copy of the font */
	  fontcopy = extract_font_range(myfont, -1, -1);
	  ...
	  destroy_font(capitals);
	  destroy_font(fontcopy);

RETURN VALUE

       Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it
       to avoid memory leaks.
