What Happens in a Split Source Window

As described in " Moving Through the Source Code", you can split the source window to display source code and the corresponding assembly code.

You can set a breakpoint in either pane of the split source window. The B appears in the line-number region of both panes, unless you set the breakpoint at an assembly code line for which there is no corresponding source line.

Deleting a breakpoint from one pane of the split source window deletes it from the other pane as well.
