Control program execution

Whether debugging multi-process code or single process code, the mechanisms for controlling program execution are very similar.

In multi-process mode, most of the features described in this section are applied using Process Groups.

For single-process mode the commands and behaviors are identical, but apply to only a single process. In this case you do not need to work with process groups.
