[scratchd] will display the content of a scratch variable and then
delete it.  [scratch] will do the same but leave the content intact.

For either of those to work, you first have to fill the scratch with
some sort of content.  You can do that using the [tmp] or [set] tag
(also available are [seti], [tmpn] and various other methods, by the
way).

For instance:

    [set foo]This is a test[/set]
    [scratchd foo]

The first line will set the scratch.  The second will display and delete.


Note that the scratch value is returned verbatim.  There is no processing
going on behind the scenes.  If you want a value to be looked up in
the database then you should use the [data] tag or something similar.

    [tmp bar][data table="products" column="description" key="SKU123"][/tmp]
    [scratch bar]

Of course, you don't need to set a scratch variable if you just want
to display the result immediately, and not store it.  The point is that
if you want something to be looked up then you must code your page that
way.
