Validation and Format Masks

When replacing a currency value specified in one currency by a currency value specified in another currency, as opposed to adding an additional currency value to the record, the currency mask should specify both a validation mask and format mask. The attributes of the value in the target currency (length, precision, and so on) can differ from the attributes of the value in the source currency. The syntax of the format mask is

%xxx=(validation mask,%yyy=(format mask))

In this syntax, xxx is the source currency and yyy is the target currency for the conversion.
