Viivi IDE States

Viivi IDE changes its state from boot-up to termination.

Main States

Initial State

	indicator-color    | state-string
	-------------------+-----------------------------------------
	N/A			   | "Click the PLAY/STOP-button to go."

Viivi IDE comes to the initial state just after being booted-up and when it restarts after termination.
In the initial state, only the controller and the argument-command window are shown on the display.
The user can make the initial-settings:

• load a project file
• edit the argument-commands in the argument-command window
  load the argument-command script file into the argument-command window
• configure the trace-mode using the trace-button on the controller
• configure the step-mode using the step-buttons (step-IN/OVER/OUT) on the controller
  (without performing any evaluations)

Clicking the enter-button or the play-button will proceed the state to the ready-state.

This state shows that Viivi IDE is ready to start processing/evaluation based on the settings in the initial state.
If it is the first session, the default IDE elements (the controller, the argument-command window, the standard-output-port window, the standard-input-port window) are shown on the display.
Otherwise, all the windows at the end of the previous session are restored (except for the I/O-port windows to be opened afterwards.
