Thus, the expression ‘<samp>melvin: .long .</samp>’ defines <code>melvin</code> to contain its own address. Assigning a value to <code>.</code> is treated the same as a <code>.org</code> directive. Thus, the expression ‘<samp>.=.+4</samp>’ is the same as saying ‘<samp>.space 4</samp>’. </p> </body> </html>
