Or, it's very similar to something else I just did, in one line...

print join("\n",@whole[0..($#whole>7 ? 7 : $#whole)]),"\n";


It doesn't pull out the carriage returns, but I was using this for 
debugging an array that I knew didn't have them.  If you know that 
each line is terminated by a return, you should be able to get away 
with...

print join("",@whole[0..($#whole>7 ? 7 : $#whole)]),"\n";


(That "7" is the number of entries you want to print out, minus 1.)
