deleting a row if a certain column is below a certain number
How can you delete a row if a certain column is bigger than a certain number?

I have the following input:

Code:
20080709 20081222 95750 1 0 0.02 94.88
20080709 20081222 95750 2 0 0.89 94.88
20080709 20081222 9575 1 0 0 94.88
20080709 20081222 9575 2 0 0 94.88
20080709 20081222 9587.5 1 0 0 94.88
20080709 20081222 9587.5 2 0 0 94.88
20080709 20081222 95875 1 0 0.015 94.88
20080709 20081222 95875 2 0 1.01 94.88
20080709 20081222 96000 1 0 0.01 94.88
20080709 20081222 96000 2 0 1.13 94.88
20080709 20081222 9600 1 0 0 94.88
20080709 20081222 9600 2 0 0 94.88

I would like to delete all rows in bold since the third column is smaller than 10000 and the result should be the lines below:

Code:
20080709 20081222 95750 1 0 0.02 94.88
20080709 20081222 95750 2 0 0.89 94.88
20080709 20081222 95875 1 0 0.015 94.88
20080709 20081222 95875 2 0 1.01 94.88
20080709 20081222 96000 1 0 0.01 94.88
20080709 20081222 96000 2 0 1.13 94.88

I have the following code in perl but is not working since I get the following error:
Use of uninitialized value in numeric gt (>) at ./format_10000.perl line 5, line 1.

Code:
#!/usr/bin/perl -w
while(<STDIN>) {
 my ( $col1, $col2, $col3, $col4, $col5, $col6, $col7 )
  = split ( /\s+/, $_ ); # split current line where you at least one space or tab...
 next if $col3> 10000;
 print STDOUT $_; # print current line. We did not chomp it, so no need for an extra \n.
}

Can anyone help me?

Thanks a lot in advance!

Pep
