LOCAL lnSuccess
LOCAL loEmail
LOCAL loMailman

lnSuccess = 0

loEmail = CreateObject('Chilkat.Email')

loEmail.Subject = "test"
loEmail.From = "bob@example.com"
loEmail.AddTo("Mary","mary@example.com")

*  Add plain-text and HTML alternative bodies.
*  Include some "=" chars so we can see the quoted-printable encoding when used..
loEmail.AddPlainTextAlternativeBody("This is a test == Hello World!")
loEmail.AddHtmlAlternativeBody("<html><body>This is a test == Hello World!</body></html>")

*  Examine the MIME of the email to see that it does not use quoted-printable.
*  (If the email contained non-usascii chars, it would automatically use quoted-printable.)
loMailman = CreateObject('Chilkat.MailMan')
? loMailman.RenderToMime(loEmail)

*  Here is the MIME before forcing quoted-printable.
*  Notice the Content-Transfer-Encoding is "7bit" (not "quoted-printable")
