- Miscellaneous features
- ======================
-
- This file describes the various odds and ends which haven't been covered
- elsewhere. Most are menu options controlling relatively minor features of
- Powerbase.
-
- Main menu choices
- =================
- Brief explanations follow for those main menu choices which have not been
- explained in any other document.
-
- Information
- -----------
- Shows the numbers of records in the six subfiles (0-6) together with the
- date on which a change was last made to each. The total number of records
- available in the database, the number in use, and the percentage usage, are
- also given.
-
- Current key
- -----------
- Gives the number of the currently-active index (the primary key index is
- always 0) and the structure of the key in the form of the descriptor(s)
- of field(s) used to construct the key (plus tag(s) if different from
- descriptor(s)) and the number of characters from each of words 1-4.
-
- Show keypad
- -----------
- Displays the keypad if you happen to have closed it or lost it behind the
- record window. If the entry is shaded then the keypad has been deliberately
- disabled by the designer of the database.
-
- Export subset
- -------------
- This enables you to export a limited selection of the records as a
- fully-functioning database. It leads to a dialogue box containing a writable
- icon into which a search formula may be typed (see 'Printing'). The name of
- the new database should be entered also (by default the name is "Subset" and
- the pathname points to 'PrintJobs'.) Dragging the database icon to a
- directory viewer results in a new database which contains only those records
- which match the search formula. Note that the passwords which apply to the
- main database apply also to the subset so this is not a method of getting
- round the password protection. It is also possible that the designer of the
- database may have disabled this option in which case the menu entry will be
- shaded.
-
- Save choices
- ------------
- Saves within the database directory a text file called 'Choices' which
- stores the status of the following options:-
-
- (1) Validate input (ticked/unticked) (See 'Validation' sub-menu)
- (2) Show relations (ticked/unticked) (See 'Validation' sub-menu)
- (3) Warn of delete (ticked/unticked) (See 'Field' sub-menu)
- (4) Save indices (Automatic, Warning, Manual) (See 'Miscellaneous'sub-menu)
- (5) In quotes (ON/OFF) (See CSV options window)
- (6) With header (ON/OFF) (See CSV options window)
- (7) Include blanks (ON/OFF) (See CSV options window)
- (8) With primary key (ON/OFF) (See CSV options window)
- (9) With field data (ON/OFF) (See CSV options window)
- (10) Separator (for CSV files) (See CSV options window)
- (11) Terminator (for CSV files) (See CSV options window)
- (12) Display (when importing CSV file) (See CSV options window)
- (13) Case specific (ON/OFF) (See any window which has a
- 'Case specific' button)
- (14) Warn of duplicates (ticked/unticked) (See 'Utilities' sub-menu off
- icon-bar menu)
-
- Help
- ----
- A fairly extensive help application to supplement the short messages
- provided via the Acorn !Help. It concentrates on telling you, briefly, how
- to actually get things done and directs you to the fuller documentation in
- these text files.
-
- Sub-menu choices off the main menu
- ==================================
-
- Field ⇨ Warn of delete
- ----------------------
- When ticked a warning message is displayed if you are about to delete an
- 'External' field, i.e. one of the types 'Text', 'Text Block', 'Sprite',
- 'Picture' or 'Draw'. When unticked deletion of the external object proceeds
- without further warning. Default state is ticked.
-
- Validation ⇨ Validate input
- ---------------------------
- When ticked fields linked to validation tables will allow only items in the
- linked column of the table to be entered. This column is called the
- validation list. When unticked all validation is bypassed and anything may
- be entered. The keystroke equivalent is SHIFT/f8.
-
- Miscellaneous ⇨ Colours
- -----------------------
- The following default colours are used to distinguish fields with certain
- characteristics:-
-
- Type Foreground Background
- ---- ---------- ----------
- Descriptor of key field (inactive) dark blue -
- Descriptor of key field (active) red -
- Data icon of primary key field - pale yellow
- Data icon of field linked to table dark green -
- All these colours may be altered by the use of a dialogue box reached from
- the above menu entry. Clicking with SELECT on the descriptor and data icons
- within this window makes either the foreground or background (depending on
- the setting of the two radio buttons) cycle through the available colours.
- Clicking with ADJUST cycles through the colours in the opposite direction.
-
- 'Apply' allows you to see the effect of the changes and 'Defaults' enables
- you to return the colours to what they were before, provided you haven't
- clicked on 'Save choices'. The latter applies the new colours and saves the
- changes so that they are effective next time the database is used.
-
- Icon-bar menu options
- =====================
-
- Save choices
- ------------
- Saves within the Powerbase directory a text file called 'Choices'. The items
- stored in this file are the same as those already listed for the similar
- entry in the main menu. Note, however, that whereas the main menu 'Save
- choices' applies to the current database only, the icon-bar menu 'Save
- choices' applies to Powerbase itself. The choices stored in this file will
- be applied to any database which doesn't have a 'Choices' file of its own.
- In other words by setting up the choices described earlier and clicking on
- the icon-bar menu 'Save choices' you are configuring Powerbase to work in a
- way which suits you.
-
- Default choices
- ---------------
- Choose this entry if you wish to return Powerbase to its original state
- after using the 'Save choices' entry just described, or to override a
- 'Choices' file which is part of the database.
-
- Help
- ----
- Identical to the main menu 'Help'.
-
- The 'Config' file
- =================
- This text file, which will be found in a subdirectory called 'Resources'
- inside the Powerbase directory,allows the user to alter certain aspects of
- Powerbase. Most users will be content with the deafault settings but special
- circumstances may indicate a change.
-
- Maximum fields per record
- -------------------------
- This defaults to 100. It may be set higher, if necessary, up to a maximum
- value of 127. Small memory savings may be made by setting it lower if all
- your databases have only a few fields.
-
- Maximum number of indices
- -------------------------
- The primary key index is always index 0 and the value in 'Config' determines
- the number of secondary indices you may define. The default is 10. If you
- never use more than the primary key you may set this value to zero.
-
- Maximum number of validation tables
- -----------------------------------
- The actual number permitted is one greater than the number in 'Config'
- (which is 19 by default). You may set the value to 0 (thus allowing only one
- validation table) but you must not set a negative value.
-
- Separator in date fields
- ------------------------
- By default this is a hyphen. You may wish to use a colon, full-stop, slash
- or other character. Remember that you may TYPE any non-numeric character
- when entering dates and Powerbase will re-format the field to use the
- character specified in 'Config'.
-
- Separator in time fields
- ------------------------
- This refers to editable time fields, not automatic time-stamps. The default
- separator is a colon. As in the case of dates, you may TYPE any non-numeral
- you like during data entry and Powerbase will reformat the time as hh:mm:ss.
-
- Launch new copy of Powerbase without closing current database
- -------------------------------------------------------------
- On the default setting (NO) double-clicking on a new database smoothly shuts
- down the current database then opens the new one. If you change the setting
- to YES then double-clicking on a new database will run a further copy of
- Powerbase, leaving the current database open. This can be useful if you want
- to access several databases at once, since Powerbase only supports the use
- of a single database. If there is a dormant copy of Powerbase on the icon
- bar (i.e. one with "No data" under its icon) then double-clicking a database
- sends it to that copy rather than launching a new one.
-
- Even with the NO setting you can load multiple copies of Powerbase by
- double-clicking on Powerbase itself and then open a different database in
- each by dragging the databases to the icons.
-
- Both here and in the entry described below it is essential to leave at least
- one space after YES or NO.
-
- Replicate search formulae in relevant windows
- ---------------------------------------------
- A search formula field and an associated 'Case specific' switch appear in
- six of Powerbase's dialogue boxes, of which the 'Match' window will be the
- most familiar. The contents of the fill-in field are normally blanked before
- the window is opened and all six operate independently. It is possible,
- however, to make an entry in one such field appear in all the others, so
- that it is already present when the window opens, and also have all the
- 'Case sensitive' switches linked so that changing one changes them all. If
- you wish to use this feature edit the final line of the 'Config' file to
- begin with YES instead of NO.
-
- Left-opening icon-bar submenus
- ------------------------------
- This feature, which is available only under RISC OS 3, causes the submenu
- arrows on the icon-bar menu to appear on the left-hand side instead of on
- the right. Submenus are therefore opened on the left by moving the mouse to
- the left. This avoids the overlapping of menus which can be something of a
- nuisance if the Powerbase icon is near the right edge of the screen. Some
- users, however, appear to dislike the left-opening menus very much so this
- feature is provided as a configurable option. Simply change the beginning of
- the line in 'Config' from NO to YES.
-
- Background colour of record window
- ----------------------------------
- This is normally colour 1 (light grey) but may be changed to any of the
- other standard desktop colours. Only the record window (not the dialogue
- boxes) is affected. The descriptors of key fields will still be light grey
- unless you alter them to match the window background.
