- THE CATALOG SYSTEM
- ------------------
-
- Bladerunner has a catalog system that serves the same purpose as the
- one in dBASE IV, which is to identify and make readily available those
- files you want to associate with a particular application or use.

- Overview
- --------
-
- The Bladerunner catalog system has two main parts: the File Viewer
- window, and one or more Catalog windows.
-
- The File Viewer shows icons for the major Bladerunner-related files in
- the current directory.
-
- A Catalog window shows icons for files in a specified catalog. A
- catalog can contain only dBASE files. (Catalog windows are not
- implemented yet.)
-
- Using the File Viewer
- ---------------------
-
- There is only one File Viewer and you can close or open it with
- standard Windows menu commands. The File Viewer is permanent; you
- canÆt create or delete it.
-
- The Search Path at the top of the File Viewer is a text field in which
- you can type the path to search; it also displays the path youÆve
- specified in the Command window with the SET PATH command. The
- Current Directory, below the Search Path, is another text field in
- which you can type the current directory; it also displays the
- directory youÆve specified in the Command window with the SET DIR or
- CD commands.
-
- Viewing Files
- -------------
-
- In both the File Viewer and Catalog windows you can choose to see all
- files or categories of files. Catalog windows show the major types of
- files you can create in Bladerunner such as .DBFs and .PRGs (but not
- supporting files such as .NDXs or .TXTs). The File Viewer shows major
- Bladerunner files, plus related files not created in Bladerunner, such
- as .WAV sound files and .BMP bitmap files. (Final File Viewer icons are
- not implemented yet.)
-
- Creating Catalogs
- -----------------
-
- You can create a catalog in these ways:
-
- - Choose File | New | Catalog
- - Double-click the Catalog icon on the SpeedBar
- - Double-click the Untitled catalog icon in the File Viewer
- - Right-click the Untitled catalog icon to open a local menu and
- choose the Create Catalog command
- - Drag the Untitled icon to the Bladerunner desktop
-
- (Some menu commands, some mouse actions, and the drag-and-drop
- capabilities of Blade Runner are not implemented yet.)
-
- You can add a description of the catalog at the time you create it. (This feature
- is not implemented yet.)
-
- To delete a catalog file, enter the ERASE <file name> command in the
- Command window, or use a file management program.
-
- Note that the above creation methods apply to only those files in the
- File Viewer or Catalog windows that Bladerunner can create.
-
- Opening Catalogs
- ----------------
-
- You open and close Catalog windows with standard Windows menu
- commands and mouse actions. You can open multiple Catalog
- windows. (Catalog windows are not implemented yet.)
-
- Adding Files to a Catalog
- -------------------------
-
- You can add a file to a Catalog window in two ways: by creating a
- file while a Catalog window is open and selected, or by dragging an
- icon from the File Viewer to a Catalog window. You can move a file
- from one catalog to another by dragging its icon, or copy the file by
- dragging its icon while pressing the Ctrl key. To remove a file from
- a Catalog window, select its icon and press the Delete key. (Dragging
- and deleting are not implemented yet.)
-
- The Bladerunner files you create are recorded in the Catalog window
- that is open and currently active. To switch recording to a different
- Catalog window, just select that window. You can disengage a catalog
- from recording by closing its window, or by selecting a different
- window.
-
- Opening Tables
- --------------
-
- When you use a Catalog window to open tables, Bladerunner handles all
- work area and alias assignments automatically. The DISPLAY STATUS
- command can show you the state of all current assignments.
-
- Viewing Non-dBASE Databases
- ---------------------------
-
- Files you create with Bladerunner appear in the Catalog window; any
- other files you might use appear only in the File Viewer.
-
- To see non-dBASE databases (collections of tables and associated
- files) from products such as Interbase, Oracle, or Sybase, you need to
- make appropriate settings with the ODAPI Configuration utility
- (included with Bladerunner). You also need to click the Database
- category selection in the File Viewer. (The Database category is not
- implemented yet.)
-
- The ODAPI Configuration utility has primary control over access to
- non-dBASE databases, including paths, and drivers. Selecting the
- Database category in the File Viewer is equivalent to using the OPEN
- DATABASE command.
-
- Each database icon in the File Viewer represents a collection of
- tables and associated files, such as queries and reports. The files
- associated with a database are displayed in the appropriate categories
- of the File Viewer when you click a database icon. The File Viewer
- continues to show ODAPI-connected, non-dBASE database files until you
- restore it to viewing the current dBASE directory. (The restoration method
- is not implemented yet.)
-
- Implementation Status
- ---------------------
-
- Catalog windows are not available yet. Catalog functionality,
- however, is available through the SET CATALOG and SET CATALOG TO
- commands in the Command window.
-
- The "drag and drop" feature for icons hasnÆt been enabled yet.
-
- Not all mouse-click, keyboard, menu, and local menu options are
- determined or installed yet.
-
- The Catalog menuÆs Add and Delete (and other) commands are not yet
- finalized.
-
- The catalog description mechanism hasnÆt been added yet.
-

- you last closed Bladerunner hasnÆt been enabled yet.
-
- The "Databases" category hasnÆt been added to the File Viewer yet.
-
- The icon designs arenÆt final.
-
- The term "File Viewer" is subject to change.
-
- The possibility of displaying lists of file names in File Viewer or
- Catalog windows, as an alternative to icons, is not yet determined.
-
- Comboboxes, or a similar mechanism, may be added to the File Viewer to
- replace the text fields for Search Path and Current Directory.
-
- The method for restoring the File Viewer to the dBASE path, after
- viewing non-dBASE databases, is not yet determined.
-
- The SpeedBar isnÆt fully implemented.
