E-mail End of Message

I have created a program that retrieves information from a file and
sends it to an e-mail recipient via the SNDDST command.  I read a line
from a file, add it to a variable, concatenate a "newline" code (x'06'),
read another line, concatenate it to the variable, etc until the end of
the file.  I receive the message intact within Outlook but if I print
the message it always prints two pages regardless of the length of the
message.  The second page is usually blank.  When I view the message in
Word, I see a page break at the end of the message.  Does anyone know of
a code that I can add to the end of the message that will signify end of
file?

Thanks in advance for any assistance.
