<p>PURPOSE:To simplify the input/output operation of an amount data, by selecting only one out of plural amounts of variable data in a storage means by an instruction from the outside when a conversion means is used. CONSTITUTION:The titled device is equipped with the conversion means which generates one data by using at least two kinds of variable data, the storage means which stores plural variable data on one side of the variables data, and a selection means which selects only one variable data out of the plural variable data in the storage means by the instruction from the outside. In other words, for example, a currency conversion rate value of each country (variable data on one side) is stored as a table, and the currency conversion rate is selected by the instruction from the outside, and the amount data to be inputted or outputted (variable data on the other side) is converted. In such a way, it is possible to omit a conventional complicated input/output operation for the amount data, and to simplify the input/output operation of the amount data, and usage in every country can be realized easily.</p> |
