If I have an array @R e.g. 
x y z
a b c
e f g
h i j

[download]
and I wish to insert a new value into the array at an initially undetermined point e.g. 
x y z
# a b c <- inserted element in position 0 
e f g
h i j

[download]
I tried doing this :- 
for my $rc(@R) {
        if ($rc->[0] eq "a") {
                splice @R, 0, 0, '#';
                print "$rc->[0]\t","$rc-[1]\t","$rc->[2]\t","$rc->[3]\
+n"
        }
}

I get this :- 
x y z
a b c
a b c
a b c
a b c
.

and so on. An endless loop
What am I doing wrong ?
