in reply to selecting columns from a tab-separated-values file

Nobody suggested Text::CSV_XS yet. If your data is straightforward: no quotations, no embedded tabs or other hiding disasters, it will be slower than a plain split on TAB, but it is very versatile when dealing with the data

use Text::CSV_XS; my $csv = Text::CSV_XS->new ({ binary => 1, sep_char => "\t", auto_d +iag => 1 }); my @row = ("") x 50; $csv->bind_columns (\(@row)); while ($csv->getline ($fh)) { my @capture = @row[0, 2, 5]; }

Enjoy, Have FUN! H.Merijn

    Good point; I have used CSV_XS to great advantage before! (However, nothing complicated about this input.)

[Lady_Aleena]: I was thinking about moving WorldBuilding to Random, since it is all randomness in that group anyway, but Random::World is the same length as WorldBuilding. I wouldn't be doing myself any favors.
