Given that this is probably Homework, I feel qualified to make the following comment: I always wonder, how do you tell the certain columns from the uncertain ones? {grin} -- Randal L. Schwartz, Perl hacker	[reply]

How about this solution using an array slice ... `my ($weight, $height) = (split(/\s+/, $_))[2,3]` [download] For further reading, have a look at perlfunc:split and perlman:perldata.	[reply] [d/l]

When is this homework due? ;) `# assuming the table you're talking # about is in a file... #read perldoc -f open open FH, "<file.dat" or die "Can't open : $!\n"; while (<FH>){ # read perldoc -f split my ($weight, $height) = (split)[2,3]; print "W: $weight H: $height\n"; } close FH;` [download] --perlplexer	[reply] [d/l]
