I have this code in my program and it's parsing a large log file. When it reaches at this point the regular expression seems to hang badly, there is a faster way to process the code to improve speed? Here is the code: 
my $p1= "iapw_p1";
my $p2= "iapw_p2";
my $p3= "iapw_p3";
my $b1= "iapw_b1";
my $p0= "iapw_p0";
my $c0= "iapw_c0";
my $c1= "iapw_c1";
my $c3= "iapw_c3";
my $h1= "iapw_h1";
my $p1b="<font color=\"navy\" size=\"2\"><b>P1</b></font><font color=\
+"#000000\" size=\"2\"><b><i> = (file inquiry - launch page)</i></b></
+font>";
my $p2b="<font color=\"navy\" size=\"2\"><b>P2</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file search - replace - operators)</i></b></
+font>";
my $p3b="<font color=\"navy\" size=\"2\"><b>P3</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file notepad)</i></b></font>";
my $b1b="<font color=\"navy\" size=\"2\"><b>B1</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file inquiry: old - owners and preowners)</i
+></b></font>";
my $p0b="<font color=\"navy\" size=\"2\"><b>P0</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file search)</i></b></font>";
my $c0b="<font color=\"navy\" size=\"2\"><b>C0</b><font color=\"#00000
+0\"e size=\"2\"><b><i> = (file search)</i></b></font>";
my $c1b="<font color=\"navy\" size=\"2\"><b>C1</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file inquiry)</i></b></font>";
my $c3b="<font color=\"navy\" size=\"2\"><b>C3</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file notepad)</i></b></font>";
my $h1b="<font color=\"navy\" size=\"2\"><b>H1</b><font color=\"#00000
+0\" size=\"2\"><b><i> = (file and arch inquiry and history)</i></b></
+font>";

for (@a_data) { 
    s/$p1/$p1b/;
    s/$p2/$p2b/;
    s/$p3/$p3b/;
    s/$b1/$b1b/;
    s/$p0/$p0b/;
    s/$c0/$c0b/;
    s/$c1/$c1b/;
    s/$c3/$c3b/;
    s/$h1/$h1b/;
