Re^4: selecting columns from a tab-separated-values file

[mildside]

Great job there Lotus1.

I'm curious about the use of splice to clear the array in your code, as below:

    splice( @$aref );

I would probably have used the below:

    @$aref = ();

Is splice faster or better in some other way?

Thanks. I started with assigning the empty array but I had a bug somewhere so I stuck the splice in and got it working. I think I forgot the '@' in the first try but put it in with splice. I don't know which is faster but it is only called a handful of times in this approach anyway.
