Re: reducing the number of lines

in reply to reducing the number of lines

Without any test data, it's hard to tell it this runs the same as your original, but...

my ($max, $cval, $inc_var, $sref, $d_or_b) =
    ($l == $k) ? ([$k,$lt], 0, undef, \@s,     $b) :
    ($l <  $k) ? ([$k,$lt], 2, \$j,   \@s_rev, $d) :
                 ([$l,$kt], 1, \$i,   \@s,     $b);
$sref->[$d_or_b+1] ||= $max->[0] - 2 if $max->[0] > 2;
$h                   = $s[$b] == 0 ? 0 : $s[$b]-1;
$s[$b1]              = max(@$max);
$c                   = $cval;
$$inc_var++  if $inc_var;
$h = $c = 0  if ( $l==$k );

Update #1: Thanks choroba, colons fixed.

Update #2: Thanks choroba again for the test script template; minor adjustments, works now.

Aren't you missing a colon somewhere?
