Greetings Monks, I have a csv file which I'll use Perl to read in and do some manipulations and then output it in a new .csv file. Snippet of the input file (not the first 3 lines of the file). Each line starts with the word "map":

Map,Axxxx,F,Bxxxx,BXXXX Axxxx,000000,000000,XXX-XXXXXXXX-XX,,NOTE:XXXX
+X Xxxxx (000000)@EX%SMTP:xxxxx.xxxxx@xx.com%X400:c=CA;a= ;p=XX;o=xxxx
+xxxxxxxxx;s=XXXXX;g=Xxxxx;,p:000000@mail,Customer Srv Centre,WORKS/ S
+RV,SUPPORT/ SUPPORT,AXD3, + 0000,(000) 000-0000,(000) 000-000,,,666 S
+nowball Paves,Vancouver,ON,CAN,J7G 3Y4,/o=O:ou=AR3/000000,
Map,...

Here is the code that I used. I am using Perl 5.8 on a Unix machine.

#!/usr/local/bin/perl

use strict;

use Text::CSV_XS;

my ($mday, $mon, $year) = (localtime(time))[3..5];
my $cdate = sprintf "%02d" x 3, $mon+1, $mday, $year%100;

my $infile = "inmap.csv"; 
my $outfile = "outmap${cdate}.csv"; 

open( INFILE, $infile);
open (OUTFILE, ">", $outfile);
    
my $csv = Text::CSV_XS->new({binary=>1});
    
while (defined(my $line = <INFILE>)) {
    next if $. == 1; 
    chomp $line; 
    if (my $status = $csv->parse($line)) {
        my @columns = $csv->fields;


            # quote columns with commas
        @columns = quotecolumn(@columns);
            
        #get email address
        for (9) {
            $columns[$_] =~ s/^.*SMTP://;
            $columns[$_] =~ s/\%.*$//;
            $columns[$_] =~ s/\".*$//;
        }

        #get street number and name        
        for (20) {
            $columns[$_] =~ s/,.*$//;
        }
        
    print OUTFILE join(",", @columns[1,2,3,4,5,9,11,12,13,15,16,17,18,
+19,20,21,22,23,24]), "\n";
    } 
}
close (INFILE);
close (OUTFILE);

sub quotecolumn {
    my @columns = @_;
    for (@columns) {
        if (/,/) {
            unless (/^"[^"]*"$/) {
                $_ = qq("$_");
            }
        }
    }
    return @columns;
}

Everything works except the getting the street number and name part. For example: for the first line, I would like the Address column to only contain 666 Snowball Paves and not 666 Snowball Paves,Vancouver,ON,CAN,J7G 3Y4. When I run the above code, it doesn't give me only the street number and name, it gives me everything. I'm a beginner in Perl and any help would be appreciated. Thanks in advance!
