Revision history
----------------------------------------------------------------

Version 1.0    First release
               Known bugs:
               - Code is not very efficient in memory usage
               - Category unit names are searched case insensitive
                 but at some places compared case sensitive.
                 This can give problems. Therefore always use same
                 case for category unit name on all cards.

Wish list
----------------------------------------------------------------

- Use variable length strings (through library calls) for the
  choice lists, so they can contain more items. Current
  maximum length of all choices in a list is 255 characters.
- If I know how, I like to use a dialog for the main window that
  can change field protections (and field lists) by just changing
  one of the lists (so not having to press Enter).
  Some of the dialogs on the Psion can do it.
- Maybe I should use something else than a dialog for the main
  window, so the menu, help and fast keys can be used while
  the main window is shown.
- Think about making Jaicnv a type 3 application, so the database
  can be selected when starting. This probably requires a
  separate directory or file extension, which makes changing the
  database with Data less easy. Its a trade-off.
- Maybe try to find out the language of the psion and choose the
  corresponding database.
- If I know how, use the help viewer as used by the standard
  Psion 3a applications, so there can be more than 8 items
  and longer descriptions, because the window contents can
  scroll.
- If I know how, try to minimize memory usage (if at all
  possible). At the moment it uses about 28 k when run, which
  is much more than the 8.5 k of the executable size and the
  (estimated) 5 k of variables. Maybe this is due to the use of
  OPL, or for buffers for databases?
- Many more different language versions (but I can not do that
  myself, because I don't know other languages good enough).
- Many more conversion (who has some).
