Hi:
Usually, when you send mail, the mail is sent using whatever settings SAS determines. So, for example, if your mail client is set to send mail in "plain text" then that is what is used for the mail content. If, on the other hand, the mail client is set to send mail as HTML content, then you could use a HTML <A> tag (Anchor tag) in the body of your mail.
For example, in regular HTML coding practice, when you want to create a hyperlink, you specify:
[pre]
<a href="http://www.sas.com">Click to go to SAS</a>
[/pre]
And, in a regular HTML page, the words "Click to go to SAS" would be underlined and in blue (indicating a hyperlink) and the <a> tag would not be visible on the HTML page.
Some mail administrators disable the sending of HTML in the body of the email. So, whether you could use an Anchor tag in the body of your mail would be up to your mail administrators. The email engine does have a TYPE= option that allows you to specify TYPE="text/html" on the FILENAME statement, but I have noticed times when I specify a type of "text/html" and if my mail client is set to Plain text, it seems like the mail client setting is used and is not overridden by SAS.
One thing you can try is to just put your URL in the body of the email as one long link -- I know it doesn't look as nice as a hyperlink, but even in plain text files, sometimes a URL that begins with HTTP:// will be OK and clickable. If you want to explicitly use an <a> tag, then you will have to check and see 1) whether you mail administrators will even allow you to send HTML mail and then if they will 2) you'll have to make sure that you code the anchor tag correctly in the body of your mail.

Or, you could work with Tech Support, because they could help you figure out the -exact- way for you to send email on your operating system and with your mail client.
