Re^5: How would I sort a two-dimensional array by multiple columns?

NetWallah, That went abit over my head. So how would your code look like?

I am not clear on how I would implement this to

input:

@toBeSorted, 0, 1, 3)

output:

@sorted

Can I see what you code would look like so that I can study the correct way?

After all this is over, all that will really have mattered is how we treated each other.

The only relevant part of the code I posted is "sub NetWallahSort". Just copy that sub into your code, and use it like: `my @sorted = sort NetWallahSort @$unsorted; # Or, simply "@unsorted", if @unsorted is an Array-of-Arrays, # rather than a reference.` [download] FYI - a 2-Dimensional array is technically an "Array of Array-references". FonkyMonk makes his declaration ($unsorted) a scalar, which is a "reference to an Array of Array-references", or "a reference to a 2-d Array". As Sienfeld would say - not that there is anything wrong with that! "As you get older three things happen. The first is your memory goes, and I can't remember the other two...
