Thanks for any help

If you are trying to insert a pagebreak every 50 lines, that's not too hard to do in perl:
Code:
$maxlines=50;
$linenum=0;
while (<STDIN>) {
  $linenum++;
  if ($linenum > $maxlines) {
    $linenum=0;
    print "^L";
  }
  print "$_";
}

(Untested)
You'll need to put an actual page break in there where it has ^L (ie don't copy-paste the ^ and the L characters, use a single control-L character).

Should do the job.

You can also do it using perl's rather nice 'format' option Perl format Primer (1/2)

control-L character is

ctrl+vl

without any pressing any shift key

The ternary if-then-else operator generally has the following syntax: E ? X : Y where E is a Boolean expression and if true, the statement is assigned the value Y.
True or False?
