Why do you usually need a word processing program? Normally, it is because you want to quickly write letters. TextMaker is a particularly efficient tool for such routine work.
All you need for such tasks is a suitable document template – that is, a document template to which an address database is assigned and in which database fields are inserted. Some such templates (for personal and business letters) and a suitable database are supplied with TextMaker.
If you use the command File | New 
to create a new document and select such a template, TextMaker automatically displays the database. Scroll to the desired recipient and click on the Insert button. The rest happens automatically. TextMaker replaces the database fields in the template with the contents of the fields from this record – in other words, the address is inserted into the text. The result is a completed letterhead, for example.
The following pages contain detailed explanations of these procedures.
Notes
Please note the following if you proceed according to the method presented here: When you Insert the selected record, the database fields in the document are physically replaced by the content of the inserted record. This means that you have created a document with a fixed record content, but the database fields themselves have been removed from the document and are thus no longer editable. (You can continue to edit the inserted content in the document, of course.)
The advantage of this method is that you obtain a personalized letter that can be saved and that does not change depending on the content of the database.
If you do not want to do this, click on the Close button instead of Insert. You can then edit the database fields of the document, switch between records, etc., as usual.
