RPL Debugging, Control Panel
The Control Panel provides buttons which are used to control the RPL execution of the RPL code in the emulator.  The project should be loaded and running (or just stopped by a breakpoint).  The buttons on this panel do the following:

 
Step In   If the next RPL instruction refers to an RPL secondary (subroutine), do one instruction advancing into the secondary.  If not at a reference to an RPL secondary, perform one RPL instruction.
 
Step Over   Perform one RPL instruction.  If the RPL instruction calls a secondary (subroutine) do the secondary at full speed and halt at the next RPL instruction of the current routine.
 
Continue   Run the emulation at full speed until the next breakpoint or the end of the program
 
Stop   Stop the emulation at the next RPL instruction encountered and enter step-by-step mode.  If the calculator is in the idle loop nothing will happen until an RPL instruction is encountered.  One way to break at the beginning of your code is to press STOP and then start the RPL code.  This produces an immediate stop.
 
Redraw   Update all panels of the RPL Debugging Window

 

RPL Execution Time
The execution time since the first RPL instruction is shown in milleseconds.

Number of Stack Items
The maximum number of items to be shown in the Stack Window can be controlled by this spin control.

ROM View 1 and View 2 Registers
The registers which control Flash Memory Page mappings are shown by these two numbers.

Next Object Window
This window shows the next RPL command to be executed when the Step In, Step Over or Continue buttons are pressed.

Stack Instructions
In the small window above the Step Over button, you may type an instruction like xDUP, xDROP, xSWAP etc. to change the stack.  These instructions are executed immediately.  Any RPL instruction can be typed such as BINT2, FALSE etc.  Items which require a compiler like text strings, numbers etc. will not work in this little window.

This is a very useful window for changing the stack, and any other calculator data item during single step operation.
