Hi All,
How to find out whether the string contains null values or empty data.
For example : I have one scalar variable $str and now I want to check
whether it contains any data or not.
What I did : If ($str eq "NULL" || $str eq " "){ print $str conatins
nothing\n";}
Is this correc

Hi Guys,
I have a little complicated problem...
I have two arrays
@a = ( ['id', 'name', 'age'],
['1', 'Fred', '24'],
['2', 'Frank', '42'],

@b = ( ['id', 'sex'],
['1', 'm' ],
['2', 'm'],
);
I want to join these two AoA, based on i

Hi: I have a string with a number of variable name, type and value pairs. I
want to split the field and build my variables. Below is an example
$string = "field1,int,10#field2,string,abc";
@values = split(/#/,$string);
I want to get two variables from the string, equivalent to the below statemen
use strict;
my $string = 'field1,int,10#field2,string,abc';
my @values = split /#/,$string;
my @vars;
no strict 'refs';
for (@values) {
my @tmp = split /,/;
push @vars, $tmp[0];
${$tmp[0]} = $tmp[2];
}
for (@vars) {
print $_, ": ", ${$_}, "\n";
}
__END__

Hello,

I am trying to use the s/// operator to remove it, by doing this:
while()

$_ =~ s/\(*\)//;
print $_;

The method used is incorrect.

Hi All,
I am trying to sort some data, which originally came as an excel file.
There are main titles, sub titles, sub sub titles and sub sub sub
titles. They defined by using different levels of indents in the
original file. I parse it and convert indents into spaces.
Main titles are sorted by f
