Hi everyone thank you so much for your help....
Thanks for the tutorials... I'm trying to correct my code ...
I've successfully tried sharing array X (when X is a one_dim array)... but I'm still having the hardest time converting this code so that array X is looks like below

X[0] = ("QWE", "RTYU" ,"IOP")
X[1] = ("QSWE", "TYU" ,"IKOP", "BVC")
X[2] = ("QE", "TYU")
X[3] = ("QSWE", "TYU" ,"IKOP", "BVC", "LMNB")
.
.
.

here is the code that works for one_dim array X

my @X : shared = ();


sub abc {
my $Var2;
.... Here the string in $Var2 gets updated everytime abc is called ....
push(@X, $Var2);
}

here is how I'm changing this

my @X : shared = ();

sub abc {
my $Var2;
.... Here the string in $Var2 gets updated everytime abc is called
push(@{X[$i]}, $Var2);
}

I'm still confused, I'm not quite sure how to share the arrays inside of X correctly.
Could you please help me with that?I greatly appreciate all your help.

thank you so much
