On Perlmonks you need to close your open code tags or else your post's formatting will be nigh unreadable. Also, your code doesn't make much sense:

#my $path = '/opt/finance/File1'; + my $path = q|/tmp/File1|; my $PMN = 'KKDDI'; my $MON = 'DDIID'; my $YEAR ='2013'; my $MON='JAN'; my $DATE='12'; my $CSV = $path . '.csv'; open CSV, ">$CSV" || die "Cannot open the file $CSV $! \n"; print CSV "\"ABCDE501,\"\"$PMN\"\",$MON/01/$YEAR,$MON/$DATE/$YEAR,$MON +/$DATE/$Y\ EAR\"\n"; # Data hash contains values that has to be printed. + foreach my $key (keys %DataHash) { print CSV $DataHash{$key}; } close(CSV);

Here you are writing the header to the CSV in a specific order but you are iterating willy-nilly over a hash which is not guaranteed to produce results in that same order.

perl -e 'my %hash = (q|first|=>1,q|third|=>3,q|second|=>2); print key +s %hash;' firstsecondthird
