I'm not entirely happy with it as it stands. The numbered $file99 variables are
ugly and are screaming for an array, but without knowing more about what you're
doing I can't improve on what you originally wrote.

But I would prefer to see list of indices declared as a constant and the data
values defaulted separately, like this:

  use constant INDICES => (3,4,6,7,12,40,41,42,43,46,56,64);

  while (<FILE>) {
    my @data = map $_ || 'default', split /\|/;
    my ($file1,$file2,$file3,$file4,$file5,$file6,$file10,$file25,$file27) =
@data[(INDICES)];
  }

HTH,

Rob
