Together with the <a href="#Iota"><code>iota</code> constant generator</a>
this mechanism permits light-weight declaration of sequential values:

	numberOfDays  // this constant is not exported

Storage-and-storage instructions such as <code>MVC</code> and <code>XC</code> are written
with the length as the first argument.
For example, <code>XC</code> <code>$8,</code> <code>(R9),</code> <code>(R9)</code> would clear
eight bytes at the address specified in <code>R9</code>.

If a vector instruction takes a length or an index as an argument then it will be the
first argument.
