You can run them in the Visual Studio debugger, just like any other  
DLL. To do so, however, is a two-part process.

Part 1: Run GME in debug mode
------------
. Set a breakpoint in the interpreters source file so you can  
actually  debug in Part 2.

. Make sure the interpreter you want to debug is set as the startup  
project (i.e., right-click the project and select "Set as Startup  
Project").

. Select Debug | Start Debugging... from the menu (or press F5). This  
should popup a dialog box asking for an executable. In the dialog, put  
the full path of GME, e.g.,

     C:\Program Files\GME\bin\gme.exe

   This will launch GME.

Part 2: Run the interpreter
---------
. Open the model you want to debug. This will load your interpreter in  
debug mode.

. Execute the interpreter you are debugging and it should stop at the  
breakpoint you set in Part 1.

Now, you can walk the interpreter's code and debug it like any other  
program in Visual Studio.

HTH,

James
