Okay, using KennethK's snippet above gives : uncaught exception from user code; snip ('4\x{a}501\x{a}\0\x{a}', '$VAR1 = undef;\x{a}')

Now the row I'm trying to get has already been printed into the data file. But running through every row in the file seems a little memory consuming when the same data should be in the array.

What seems to be happening is is  @{$aob[ $y - 1 ]} just isn't getting me the row from the array.

In a different subroutine I have $aob[$x][ $y - 1 ] and there are always values there and it works properly - it's getting that entire row ($y - 1) into a separate array so I can get the mean of the row that's giving me problems.

The code for getting the row comes from Dennis's Quick Guide and I haven't found that particular algorithm anywhere else.

It would be nice to get the row algorithm to work as a one-liner. But it would be even nicer to just get it to work.
