<p>The generic function block where you can write code to do more interesting things.</p>
|
|
<p>You can have multiple outputs - in which case the function expects you to return an array of messages... <pre>return [msg,msg2,...];</pre></p>
|
|
<p>You may return null for any or all outputs if you want to.</p>
|
|
<p>You can save your functions to a library (button to right of name field) - and likewise pick from that library.</p>
