 After starting the debugger the emulation will stop at the current program counter position. The emulation will continue after closing the debugger window. Please remember that the clock now shows the wrong time.
 1.) System Menu / Debugger Settings
-1.) Menu Debug
+This is the configuration dialog for the debugger.
 In the "Disassembler" section you can switch between HP and Class Mnemonics for the disassembler. This switch is exactly the same like in the main Settings dialog.
 In the "Symbolic" section you can setup the debugger for symbolic debugging. Therefore the debugger needs a reference file. The reference file must contain a table for converting an absolute address into a symbolic name. I decided to use the HP-TOOLS object files (file extension *.o) with the supported entries. These object files are usually provided by HP for the HP48 and HP49 series and are necessary for linking object files. In the case of older calculators you have to make them by your own. Using the object file for the linker as reference has two disadvantages. First such an object file has an assembler specific output format, in our case the debugger only understands the output format of HP SASM v3.x. Second, in some cases an entries has two or more different names and I cannot control which name is returned.
 Example from ENTRIES.A (HP48 Supported ROM Entry Points)
 =UNROT    EQU #60FAC *
 =3UNROLL  EQU #60FAC *
 =XYZ>ZXY  EQU #60FAC *
 My implementation returns the last name inside the linker object file to the chosen address.
 If you don't have the linker object file, the HP28S entry point list for example is only distributed as assembler source file SUPROM28.A, you can simply generate it with
 sasm -N SUPROM28.A
 - Enable
 With an unchecked Enable check box you can disable the symbolic debugging without removing the reference file.
 - Model
 Each calculator model needs his own symbol reference file. The given models exactly corresponds to the one used in the KML script. When you opening the settings dialog automatically the actual model is chosen in the combo box. You can switch to all other possible calculator models to enter the corresponding reference files. When you exit the dialog with the Ok button all filenames are saved.
 - Edit field
 The edit field must contain the filename to the model specific symbol reference file which is chosen by the combo box.
