Hi Perlmonks... I am very confused with the quotes '"'in Perl.. Actually.. when I want to print or search '"' in some var, do I have to use \" instead of only ". Actually I have tried using \" but it still give me some error. Below are input and output file: 
INPUT

DATE     13-JUN-2000
COMMERCIAL SUPPLIERS
SEQUENCE             
                     /exon="49-333"
                     /intron="1-48;334-385"
                     
//

                     /exon="1-120"
                     /intron=" "
//

OUTPUT   EXPECTED

Intron    (Translation%334-385}

DATE    "14-JUN 2002"
Exon    {Translation -}
Intron    {Translation%1-120}

REAL OUTPUT

This is my code: 
#!/usr/local/bin/perl -w
# A program that accept an input file: Scorpion database from Gen Bank
# and will output the database in BioWare format

my $file1="$ARGV[0]"        #var to save the input database
my $result=">".$ARGV[1];
my $counter=1;

open(INFO1,$file1) or die "Can't open $file1.\n";#open file1
open(OUT,$result) or die "Can't open $result.\n";

#foreach line in the files
foreach(<INFO1>)
{
if(/^DATE\s*(.*)-(.*)-(.*)/){
   print 'DATE'."\t".'"'."$1-$2-$3".'"'."\n";
   }                                             
elsif(/\s*\/intron=(.+)\n/) {
   my $item;
   my $local=$1;
   $local =~ s/\"//g;
   foreach $item (split('\;',$local)) {
          print "Intron\t \{Translation%$item\}\n";
        } #end foreach
    } #end elsif
                                       
elsif(/\s*\/exon=(.+)\n/) {
   my $item;
   my $local=$1;
   $local =~ s/\"//g;
   foreach $item (split('\;',$local)) {
   print "Exon\t", " \{Translation\%","$item\}","\n";
        }#end foreach
    }#end elsif          
}

I have also tried to put the date together in one string: 
 print "DATE\t \"$1-$2-$3\"\n";

But it also give me the same result as above.

The Gory details of parsing quoted constructs ( in perldoc ) doesn't really help me. Is there something wrong in my code? Thanks so much...
