Note: Applications that are to be debugged using the Source Debugger need to have additional information generated at compile time to allow the Source Debugger to map in-memory modules to source code. These "symbolic" reference files are generated by clicking the VAM's "Properties" button, and selecting the "Generate Debug Symbols" checkbox featured on the "Application Properties" dialog. You must then re-compile the entire application. Enabling the generation of symbolic references for the Source Debugger does not alter the generated module code, but reduces compilation speed. For production code, you can generate a set of debug symbols (held in .SYM files in your application directory), and simply archive them with your set of VTS application source code files. Later, if you should discover a problem on a production machine (that just contains the .RUN files produced by the compiler), you can simply copy the source and symbol files to the application directory on the target machine and use the full capabilities of the Source Debugger. If you do not have a set of .SYM file, you can still use the Source Debugger, but you will not be able to place breakpoints or position the source code for the currently selected module accurately.
