how to add to a record list manually?

<br />how can I add a record to a record list?
<br /><br />I cannot do it via the database, because I don't know certain values yet.
<br /><br />so I have a local variable with data-type "Record List" and I want to "add" a record to that list.
<br />Is that possible with an assign?
<br />

never mind, found it ;)
