Dear Perlmonks,

I have written a perl code which is giving wrong results. I need your help to sort out this problem.

From an array, I am interested in getting the substrings starting with either A or G, followed by TG, followed by any number of characters, followed by T, followed by A or G, ending with A or G i.e. AGTG.*TAGAG

#!/usr/bin/perl -w
# Finding substring starting with [AG]TG followed by any number of cha
+racter but ending with T[AG][AG].
# Getting the output of each substring, its length and locating its po
+sition from left to right 
# by number with starting position as zero
@d = “CCATGNNNTAACCNNATGNNTAGCC”;
use 1.010; 
my $string ="@d";
# Remove whitespace 
$string=~ s/\s//g;
 $x= () =$string=~ /[AG]TG.*T[AG][AG]/ig; 
say $_ for map{("%d('%S')",length,$_)}split/$x/,$string; 
my @a=$_ for map{("%d('%S')",length,$_)}split/$x/,$string; 
print "The sequences and their lengths are:\n  @a \n";   
exit;

Result: I am getting the following wrong result from cmd:

Microsoft Windows Version 6.1.7600

Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Users\DR-SUPRIYO>cd desktop

C:\Users\DR-SUPRIYO\Desktop>perl2.pl

Can't call method "say" without a package or object reference at C:\Users\DR-SUP RIYO\Desktop\perl2.pl line 11.

Correct Result should be like this:

The sequences , their lengths and positions are:

ATGNNNTAA; 9; 2-10

I hope perl monks will help me get the correct result.
