Convert is a program for calculating currency conversions.  It
is intended for use by travellers or for simple conversions
only.  It does not cater for differential buy/sell rates,
commissions or exchange charges.

Convert allows for the maintenance of currencies and exchange
rates in a database file and for the selection and use of any 6
of these at one time for conversions.

Convert allows for the selection of any one of the currencies in
the database as the master currency.  This is used as the basis
for all conversions and conversion rates should be entered
against this currency.  If this currency is changed, the rates
of all other currencies in the database are recalculated
automatically.

Currencies in the supplied file are:
Sterling, Dollars, Drachmars, Marks, Francs, Lire, Belgian
Francs, Australian Dollars, Austrian Schillings, Canadian
Dollars, Finnish Marks, New Zealand Dollars, Norwegian Kroner,
Escudos, Swedish Kroner, Cypriot Pounds, Swiss Francs, Yen,
Guilders, Danish Kroner, Irish Punt, Hong Kong Dollars and
Pesetas.

Installation

Convert requires that the data file CURR.DBF is situated in the
"\DAT" directory of the Series 3 and, if you wish to install
Convert as an application, the pic file CONVERT.PIC is situated
in the "\OPD" directory.  If you don't wish to install convert
as an application, CONVERT.PIC is not needed and you should
delete or "Rem-Out" the first 3 lines of the CONVERT.OPL
program.  Once the files are in place, you should open Convert
under the OPL menu and translate it.  If you are using it as an
application you should then choose install application from the
system menu, otherwise you can run CONVERT from the opl
applications menu.

that all rates will be converted to the new master currency, and
then a dialogue box allowing for selection of a new master
currency from all currencies in file.  The maximum list allows
for the currency names to total no more than 255 characters
including a spacing character.  The program then starts the
process for selecting 6 default currencies. (See below).
Convert then displays a message while converting all exchange
rates to the new currency.

This allows for the selection of the 6 default currencies and
their associated hot keys.  The hot keys may be any character
