- Copyright subsists in all versions of Powerbase. We reserve the right
- to withdraw support and authorisation to distribute Powerbase.
-
- No warranty, express or implied, is made about the suitability of
- Powerbase for any purpose. We can not be held responsible for any loss
- or damage to your health, wealth or marriage due to the action or
- inaction of Powerbase.
-
- Powerbase is shareware. You are allowed to copy it freely as long as
- you do not do so for any profit, and that the application is kept
- intact and unchanged. If you find you use Powerbase on a regular
- basis, you should register your copy with us. For £10.00 you will get
- support and “free” upgrades. When registering please say whether you
- require a RISC OS 2 or RISC OS 3.1 version. The latter has some extra
- features not found in the former. Further changes to the RISC OS 2
- version will be limited to fixing reported bugs.
-
- Updates are supplied as needed rather than on a regular basis. If you
- encounter any problems or need an additional facility, please send a
- disc with the program and database that you are using and give as much
- information as possible about how and under what circumstances the
- program misbehaves. (It is not possible to give a meaningful answer
- to a letter that says merely "it doesn't work" !) If you have an
- unusual system (eg colour card, RO2, RiscPC) please let us know.
- Limited telephone support is available most evenings and sometimes
- during the day.
-
- New users of Powerbase do unexpected things, and reach parts of the
- code the programmers don't normally use. Because of the feedback we
- have recieved, minor upgrades have been appearing almost daily,
- amounting to a major upgrade about every six months. Also, some nice
- people have sent us small (like !Friends and !Boxes) sample databases,
- and we would be pleased to receive more, or user functions or
- Powerbase-specific utilities for distribution in the public domain.
- To receive the latest version of Powerbase, just send us a formatted
- disc (E format or HD) or four first class stamps. If you would like
- any extras, please tell us which ones you already have.
-
- Direct mail-merge is implemented for Impression, including Publisher
- (v4.01 onwards) and Style (v3.03 onwards), and two sample files are on
- the disc. Ovation uses CSV files for mail-merge, and a sample file is
- on the disc. CSV (comma separated value) files are also useful to
- transfer data to text editors (ie Edit and StrongEd) which do not
- support mail-merge.
-
- Powerbase is unlikely to run from an archive or to use an archived
- database: !CDList in the Examples archive gives a buffer overflow error
- instead of loading. Powerbase is also unlikely to run from CFS.

-
- The database !Elements is used extensively as an example in the
- tutorial, and !Friends is used in the quick tutorial. Other example
- databases are available to show the flexibility of Powerbase.
-
- Major updates will be sent to Arcade BBS, APDL, and to the Datafile PD
- Library.
-
-
- Powerbase users should be aware that the use of a database to store
- personal details other than those of immediate family members may
- render them liable for registration/compliance with the provisions of
- the Data Protection Act. (Data Protection Registrar, Springfield
- House, Water Lane, Wilmslow, SK9 5AX. Tel. 01625-535777)
-
- Important note to existing users of versions prior to 4.93 (NOT 4.993!!)
- ========================================================================
- v.4.93 was the first to allow indices to be case sensitive. If you create
- a database using that, or a later, version and try to run it on any
- version of Powerbase prior to v.4.93 an error will occur. It is usually
- either “String too long” or “Address exception”. The problem is most
- likely to afflict a user who is given a database by someone using a recent
- version and who then tries to run it on an earlier one.
-
- It is also possible for a database created with, and working
- satisfactorily with, a pre-4.93 version to suddenly start giving errors
- after being used on a later version. This will only happen if indices have
- been created, or the primary key rebuilt, under the later version.
- Deleting the contents of the Indices directory may then put matters right.
- If it doesn’t then rebuilding the primary key under the older version
- will.
-
- The problem was alleviated somewhat in v.4.98. Databases created with this
- will work on earlier versions of Powerbase provided you do NOT make any
- index case-sensitive.
-
- The best solution, of course, is to send us a disc with sae (or 4 first-
- class stamps; discs don’t really enjoy postal journeys) and ask for an
- upgrade. There is NO problem running databases created with a version
- EARLIER than 4.93 under a version LATER than 4.93.
- =========================================================================
-
- NOTE for RISC OS 2 users
- ========================
- Some versions of Powerbase give an error during initialisation. This is
- apparently due to a bug in RISC OS 2 which causes corruption of the BASIC
- stack if a window template with a name shorter than 4 letters is used.
- (No, I don’t understand it either!) RISC OS 3 doesn’t mind such short
- template names at all. If any RISC OS 2 user experiences problems, please
- write for version 5.24 or later.
