You need to qualify the type of memory. It reads stdin into *virtual*
memory. It's the amount of disk you have that limits the size, not the
amount of RAM. Just add swap space. You may prefer to use a 64 bit machine.

Are you aware of any limits?

I didn't see that in the req spec :-P  You can complicate the program
with a print "\n" or somesuch if you must.

Karl's fix for that works  local $/ = undef;

Cheers, Dave

PS  I sent the prog for fun, don't take it too seriously.
