- Each Module in the Shelter Island Press system is acutally a stand-
- alone database comprised of a MainFile and several possible SubFiles.
- Within each Main File are individual records or data cards. Imagine this
- as nothing more than an electronic file cabinet with different drawers for
- each Tracking Module.

- MAIN FILE
-
- The Main File is comprised of ALL members of the tracking area (e.g. ALL
- foods). To add a new member to a file you simply choose the (F)ile
- command from the top menu line and then choose the (A)dd submenu item.
-
- SUBFILES
-
- A SubFile is actually a sorted file compiled from the Main File. For
- instance if you wanted a list of all vegetables in the FOOD file you would
- search the Main File for that criterion. Once this SubFile has been
- sorted you may save it to the disk as a semipermanent database. You may
- add a record to any subfile. However when you add to a Subfile the Main
- file is automatically updated also. In this manner the MainFile always
- remains current. There is really no limit (other than the storage
- capacity of your disk) to the number of SubFiles you may compile. For
- help on setting up a sort see the help menu item SEARCHING & SORTING.
