@_ refer to the whole dataset right?

Do a ctrl+f for spankTheMonkey to see what spankTheMonkey is being given (which args are passed)

Then see perlvar#@_ Within a subroutine the array @_ contains the parameters passed to that subroutine.

So, @_ is not "the whole dataset", there is no variable "the whole" of type "dataset" :)

But if I want to only include data from column 4 onward to the end, I have to write a function to split the data and then take column 4 to end and put it into @_?

Yes, you can modify spankTheMonkey to discard parts ... essentially turning it from readFullData into readColumnRange( $in_filehandle, 4 .. 10 );

perlintro#Arrays ought to help
