File Manipulation (Move Column Position)

Hi All,
I have a comma separated value (.CSV) file like the one below. The file contains about 20000 lines.

FileName
EmpNo,Name,Age,Sex,Band,Spouse,Children,Salary,
1000,Arnold,24,M,B,N.A.,No,10000,
1001,Jenny,27,F,C,John,2,20000,
...................................

What i need is to make a new file which has Salary as the fourth column.

FileName2
EmpNo,Name,Age,Salary,Sex,Band,Spouse,Children,
1000,Arnold,24,10000,M,B,N.A.,No,
1001,Jenny,27,20000,F,C,John,2,
..........................................

How can we accomplish this by making use of "awk"? Any sample code is most welcome..

Thanks in advance,
Ultimate

NAME
AnyData::Format::CSV - tiedhash & DBI/SQL access to CSV data SYNOPSIS
use AnyData; my $table = adTable( 'CSV', $filename,'r',$flags ); while (my $row = each %$table) { print $row->{name}," " if $row->{country} =~ /us|mx|ca/; } # ... other tied hash operations OR use DBI my $dbh = DBI->connect('dbi:AnyData:'); $dbh->func('table1','CSV', $filename,$flags,'ad_catalog'); my $hits = $dbh->selectall_arrayref( qq{ SELECT name FROM table1 WHERE country = 'us' }); # ... other DBI/SQL operations DESCRIPTION
This is a plug-in format parser for the AnyData and DBD::AnyData modules. It will read column names from the first row of the file, or accept names passed by the user. In addition to column names, the user may set other options as follows: col_names : a comma separated list of column names eol : the end of record mark, by default quote_char : the character used to quote fields " by default escape_char : the character used to escape the quote char, " by default If you are using this with DBD::AnyData, put ad_ in front of the flags, e.g. ad_eol. Please refer to the documentation for AnyData.pm and DBD::AnyData.pm for further details.
