Hmm .. happens for many such no.'s , but of different length
I think it's calling some functions of Word.
=rand(no. of lines, no of times to repeat in each line)
however there seems to be an upper limit, it seems to be ::
(no. of lines + no. of times to repeat in each line ) < 300
AND no. of lines <= 200 AND no. of times to repeat in each line <= 200
AND no. of output lines < 1000
