Remarks

Exchange table

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.

This exchange table is as follows:

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 popup 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.
