Joe Litton has written some LotusScript code to programmatically create a memo with a doclink on top and the signature of the current user on bottom. He used a modified InsertSignature function (originally from the CoreEmailClasses script library).

But there is a much shorter solution using the formula language, if the doclink should link to the current document or the document currently selected in the current view:

@Command([EditMakeDocLink]);
@Command([Compose]; @MailDbName; "Memo");
@Command([EditGotoField]; "EnterSendTo");
@Command([EditInsertText]; "Lists of recipients...");
@Command([EditGotoField]; "Body");
@Command([EditInsertText]; @NewLine + @NewLine + "Further text..." + @NewLine);
@Command([EditGotoField]; "Body");
@Command([EditInsertText]; "Click on this link to open the referred document: ");
@Command([EditPaste]);

Text inserted after the @Command([EditPaste]) is always inserted before the doclink! Thus you have to write the text, which should appear after the doclink first, than re-enter the body field, write the text before the doclink and than paste it.

This solution also solves the problem, that if the user closes the memo without sending it, it does not leave is unwanted draft document.
