- databases will be sent on request; just send a disc and tell us which
- ones you already have. Powerbase is unlikely to run from an archive or
- to use an archived database.

- 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 flexiblity of Powerbase.

- Major updates will be sent to Arcade BBS, and to the Datafile PD Library,
- APDL, ArchAngel, and RiscUser.
-
- 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.
