| <samp><span class="command">as</span></samp> is assembling into. Thus, the expression ‘<samp><span class="samp">melvin: |
| .long .</span></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><span class="samp">.=.+4</span></samp>’ is the same as saying |
| ‘<samp><span class="samp">.space 4</span></samp>’. |
