| ==Usage notes==
| |
| <ul>
| |
| <li>Using a null <var class="term">string</var> for <var class="term">onBits</var> is an easy way of turning on a specific set of bits for each byte in a string (the <var class="term">pad</var> value).
| |
| <li><var>BitOnString</var> is most useful for working with binary data, for example binary data being sent or received with <var class="product">[[Janus Sockets]]</var>.
