Paradox Memos/ database desktop

Hello

Can anybody please help me with, what I realise, is a very
straightforward and simple question?

How can I edit memo fields from within Database desktop?  Is it
possible?

Secondly.  How would I add lines to this memo from within my Delphi
code?  I have looked through every manual and book in search of an
answer and, have until now, found precisely nothing.

In anticipation and many thanks
