摘要

A data control device includes: an execution means that executes, as an active runtime environment, one of a plurality of runtime environments each provided with an individual clipboard used for data reading and writing; a switching means that switches the active runtime environment; a decision means that, when the active runtime environment is switched by the switching means, decides whether an item of data written to a clipboard of a runtime environment that is active before the switching should be copied to a clipboard of a runtime environment that will become active after the switching, by referring to an attribute of at least one of the runtime environment that is active before the switching and the runtime environment that will become active after the switching; and a management means that manages copying of the item of data between the clipboards based on the decision made by the decision means.
