To <I>create</I> a user table one can also use the <TT>CREATE/TABLE</TT> command by giving <TT>NULL</TT> as input. This will create a table of the specified size where all elements are <TT>NULL</TT>. Columns in a table can be created or deleted by using the commands <TT>CREATE/COLUMN</TT> and <TT>DELETE/COLUMN</TT>.
