Phil, Thank you for your reply.  However, I don't know if I could use the
tr command because I'm trying to delete null charachters form a VARIABLE,
not a text file.  Can the same command be used?  If not, is there another
command that can be?

Anyone can answer that!!!!!   Thanks..............Lucy

Hi again Lucy,

You'll need a $ in front of the open bracket on the first_line and
second_line lines!
