Ciao Ulla

My password generator has been sent out before,

you must run it in a system that has the korn shell though.  If you have the 
ksh shell in a directory other than /usr/bin, then you will need to edit the
first line of the script.

It is a script and the syntax is:

	random_generator <password_number> <number_of_characters>

It is very random on creating passwords, as it uses randoms to create
randoms.

May not be what you want, but it may be of use.  Tell me if it could
be improved.
