Hello Raghu,
I am sorry, just now only I checked your mail. Anyway regarding your question, it is very easy in Perl.
Use the grep command in perl. It works like a filter.
I will give you a small example.
@a = (123, adf, 1, 345, r);
@b = grep { /1/ } @a;
$x = join(”\n”, @b);
print “$x\n”;

OUTPUT
123
1

So virtually you can give any condition there.
Similar to this is map command.
Both are very powerful features in PERL,

Try man perlfunc, you will get all the details.

Thanks

In TCL there is a solution by lremove [ lsearch $element $array ] ] $array

in perl also we can do in this as @a = ($a[0..3],$a[5..6])
