 %I% If you want to know if a field is undefined (has never been given a value) then you can compare it with =undefined= (this requires that no field called =undefined= exists in the form).
 
-%I% In the operators (<code>&#61; !&#61; ~ &#61;~ &lt; &gt; &lt&#61; &gt&#61; NOT AND OR</code>) an undefined operand is treated the same as numerical 0. For <code>lc uc d2n an undefined operand will give an undefined result. For =length= and undefined operand will give a result of 0.

 ---++ Text and Meta Text
 There are two fields that contain the topic text, =text= and =metatext=. =text= just contains the raw text of the topic, as you would see if you viewed the topic raw. =metatext= contains the text of the topic with MetaData embedded. This can be useful when you want to generate output based on processing meta-data.
