I have a file (called in.txt) that is formatted with field demiliters and text like this: BEGTITLE blah,blah...blah ENDTITLE. The title field is followed by other fields delimiteted the same way. I have been assigned the glorious task of replacing specific words or useless metacharachters only between the title tags, leaving all other instances untouched. I have tried various methods with zero luck (this will probably not be surprising to an experienced PERL programmer!). Here is a sample of my code and INFILE: 
Sample in.txt
BEGPUB Wirey Haired Dog's Life ENDPUB
BEGTITLE My dog has wirey hair ENDTITLE
BEGTXT My wirey hair dog...blah, blah. ENDTXT

My Script 
#!/usr/bin/perl -w

open(INFILE,$ARGV[0]) or die "INFILE CROAKED";
open(OUTFILE,">$ARGV[1]) or die "OUTFILE CROAKED";

While(<INFILE>){
        while(/BEGTITLE.*wirey.*?ENDTITLE/){
        $_=~s/wirey/smooth/i;
        print OUTFILE $_;}
        }
close INFILE;
close OUTFILE;

I want to replace wirey with smooth in just the title field (which may span multiple lines). My example will replace the word wirey in the other fields as well. I have no basis to believe that my code is anywhere near being correct or useful. I do not even know why I though this could lead anywhere good. Any ideas or suggestions will be much appreciated. Thanks in advance, Stephen
