!! Using the Set Widget to Create Global Variables
There are times when it makes sense to use the features of the [[SetWidget]] rather than procedures or functions to create global variables. This can be accomplished by placing the set variable widget in a tiddler that is tagged [[$:/tags/Global|SystemTag: $:/tags/Global]]. If multiple variables are required, the set variable widget can be nested as shown here:
<<<
<div class="doc-example">
```
<$set name="myGlobalVariable" value="I am global">
<$set name="myOtherGlobalVariable" value="I am also a global variable.">
</$set>
</$set>
```
</div>
<<<
