Syntax
<Result> = eExchangeRate([<Currency>])
<Result>: Currency
Value of the exchange rate for the specified currency.
<Currency>: Integer or constant (optional)
Identifier of the currency or constant associated with the currency (see the Notes). If this parameter is not specified, the function returns the value of the exchange rate of the currency which identifier is "1" (the French Franc by default).
Remarks
An exchange table is stored in memory. Each currency is associated with:
- A currency number used to identify the currency by programming.
- A constant used to identify the currency by programming.
- A caption (up to 7 characters): this caption is displayed in the "Currency + Euro" control if the input mask allows it (the $ sign is indicated).
- An exchange rate. This exchange rate corresponds to the exchange rate of the currency in relation to the Euro.

The first currency (whose identifier is set to 0) is the currency used as reference for the conversions.
In this exchange table, you have the ability to:
- add new currencies by modifying the custom currencies if necessary ("user-defined currencies" from 16 to 25) with eInitCurrency,
- specify the exchange rate of each currency with eInitCurrency.
Caution: The currencies whose exchange rate is set to 0 will not be displayed in the context menu of the "Currency + Euro" control. To define the exchange rate of these currencies, you must redefine them in the initialization code of the project with
eInitCurrency.
