Hi, I'm reading in a 19MB Rich text file (Student's report card) using 
open(RTF_FILE, "file");
while(<RTF_FILE>){   
   $document.=$_; 
}
                
$document =~ s/SURNAME/$surname/ ;
....
....

print $document ;

I have about 20 of these matching lines of code. At first I had the matching lines inside the while loop. Opening a document took about 30 secs, now with it on the outside it takes about 5 secs. Is there a better way to do this? Scott
