### Start Debugging a DLL from a Source Window

You can start debugging a DLL used by your application from the Source window containing the current execution point, provided you can use step commands to reach a statement that calls a function within your DLL.

1. In the Source window, use a combination of breakpoints and Run, Step Debug, and Jump to Location commands to execute or skip over portions of your code, up to the call to the DLL function you want to debug.
2. Issue a Step Into or Step Debug command to enter the DLL function.

A Source window showing the DLL function is raised, and the current line is the first line within the function.
