    // We want to build a multipart/alternative email, where the 1st alternative body
    // is text/plain, the 2nd is text/x-amp-html, and the last is text/html.
    // (Some email clients will only render the last MIME part, so we recommend placing the text/x-amp-html MIME part before the text/html MIME part.)

    // First create a plain-text email body:
    Get ComAddPlainTextAlternativeBody Of hoEmail "Hello World in plain text!" To iSuccess

    // Now add the text/x-amp-html.
    Get ComGetAsString Of hoSbAmp4Html To sTemp1
    Send ComSetTextBody To hoEmail sTemp1 "text/x-amp-html"

    // Now add an HTML body..
    Get ComAddHtmlAlternativeBody Of hoEmail "<span>Hello World in HTML!</span>" To iSuccess

    // See what we have:
    Get ComGetMime Of hoEmail To sTemp1
    Showln sTemp1

    // This is the result:
    // (Note: Any CKX- headers produced by Chilkat are automatically removed prior to sending.)
