in thread pseudocode for getting data from table

That is under-specified. What is the table layout? Spaces only or tabs? With TAB's, have a loog at Text::CSV and it's faster parent Text::CSV_XS. If spaces only, you have a problem, as the first line is not aligned with the rest. If it were, pack/unpack would most likely be of help:

# Example using split on multiple spaces open my $fh, "<", "INPUT"; while (<$fh>) { $. < 100 and next; chomp; my ($typ, $gid, $org, $lvl) = split m/\s\s+/ => $_; say "$. $gid, $lvl"; } close $fh; # Example with TAB's use Text::CSV_XS; open my $fh, "<", "INPUT"; my $csv = Text::CSV_XS->new ({ binary => 1, sep_char => "\t", auto_dia +g => 1 }); while (my $line = $csv->getline ($fh)) { $csv->record_number < 100 and next; my ($typ, $gid, $org, $lvl) = @{$line}; say "$. $gid, $lvl"; } close $fh; # Example with unpack (I manually aligned the header line) open my $fh, "<", "INPUT"; while (<$fh>) { $. < 100 and next; chomp; my ($typ, $gid, $org, $lvl) = unpack "A25 A10 A26 A*" => $_; say "$. $gid, $lvl"; } cloase $fh;
