Hm. I put the code and data from your post together into a single file and it worked perfectly:

 #! perl -slw
use strict;

#open DATA, "test2.txt" or die "Cant open file";

print "Receiptno. Consumer name           Consumer no. Subdivision    
+ Type of work     Phase     Cheque no.   Amount";

printf "%-11s %-23s %-12s %-14s %-16s %-10s %-11s %-14.2f\n",
    m[
        ( [0-9\.]+ )\s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( [0-9\.]+ )\s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( [0-9\.]+ ) \s+
        ( \S+ (?: \s \S+ )? ) \s+

    ]x

    while <DATA>;

So I suspect that your data file does not contain a final newline.

If you want to do something with the values captured, other than just print them, you'll need to assign them to some variables. A minor reworking of the code--which was posted as an example for you to learn from , not to be used verbatim--and you get:

 #! perl -slw
use strict;

#open DATA, "test2.txt" or die "Cant open file";

print "Receiptno. Consumer name           Consumer no. Subdivision    
+ Type of work     Phase     Cheque no.   Amount";

my $total = 0;
while( <DATA> ) {
    my @caps = m[
        ( [0-9\.]+ )\s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( [0-9\.]+ )\s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( \S+ (?: \s \S+ )? ) \s+
        ( [0-9\.]+ ) \s+
        ( \S+ (?: \s \S+ )? ) \s+

    ]x;

    printf "%-11s %-23s %-12s %-14s %-16s %-10s %-11s %-14.2f\n", @cap
+s;

    $total += $caps[ -1 ];
}

print "Total: $total";

Which may or may not be what you want, but even if it is, please try to understand what it is doing and modify it for your purposes rather than just coming back each time you need a change. You really should have been able to work that out for yourself. I'm unlikely to be so accomodating next time.
