The Dm functions let you specify a category number. You can get and set the
category number of a record, or iterate through all records in a given
category number. These are independent of the Category functions...
The Category functions assume the category names are in the app info block.
They let you assign category names to category numbers. You probably don't
want to store category names anywhere, so you don't need to use the Category
functions at all.
BeamBooks stores "Books I Have" and "Books I Can Get" as records in a
database with category numbers 1 and 2. It uses a pop-up list to choose
between them, but it could have used push buttons just as easily.
