You can navigate to any file dbx recognizes as part of the program (even if a module or file was not compiled with the -g option). To navigate to a file:
(dbx) file filename |
Using the file command without arguments echoes the file name of the file you are currently navigating.
(dbx) file |
dbx displays the file from its first line unless you specify a line number.
(dbx) file filename ; list line_number |
