Is this the correct...

$myRange  ne  $readSz?

    The idea in my brain was that $myRange = the range of bytes required, and $readSz = the buffer size. But maybe that got lost in translation into Perl ?

      You could try something like:

      use constant READSIZE => ...; my $fh = ...; my $start = ...; my $end = ...; ## check $end < -s($fh)! seek $fh, $start, 0; while( ($_ = tell( $fh ) ) < $end ) { local $/ = \min( READSIZE, $end - $_ ); my $chunk = <$fh> or die $!; ## ... }
