is there a way of specifying certain columns to be printed? e.g the 10th,18th and 20th column? One way to do it - use an array slice: `{ local $" = "\t"; print $OUT map "@{$_}[10,18,20]\n", sort { $a->[10] cmp $b->[10] } @ +out; }` [download] See References quick reference.	[reply] [d/l]

where can i read up on in regards to skipping blank/empty values when splitting arrays? Something is wrong wrt your question, since you don't split arrays, you slice or join them. Do you mean omitting empty fields splitting a record, or omitting empty/undefined array elements joining an array?	[reply]
