in reply to non numeric data

I would assume your data is not what you think it is:

#!/usr/bin/env perl use strict; use warnings; my @array_H = ( 'ABCD', 1234, '1234', ' 1234' ); foreach my $ele ( @array_H ) { if( $ele !~ /^[0-9]+$/ ) { block( $ele ); } } sub block { my $ele = shift; print "Woot -- $ele --\n"; }
Woot -- ABCD -- Woot -- 1234 --

    ya i figured that out , there is a possibility that numbers having - sign are not being blocked so I modified by code . please tell if it is fine or not

    if (($array_H[$i] !~ /^[0-9]+$/) &&($array_H[$i] !~ /^-+$/))

    I am new to perl so please pardon me for obvious mistakes

      Depending on the source of your data, it may have whitespace (especially a newline) at the end.
