Kheops has very simple text based user interface. It could be compared to a Unix shell (as a matter of fact very user unfriendly one, without even the history capabilities).
There are three modes of operation: Supervisor, Interpreter and Executer. When started, Kheops is in Supervisor mode. It allows the user to load, unload or compile an application or to change current mode invoking Interpreter or Executer.
Interpreter and Executer modes are for testing and debugging purposes. Interpreter works on the decision tree generated from an application while Executer uses generated executable.
All modes offer access to information about current status of loaded application.
