Do not show address for (pseudo) instructions with no code
While such instructions do not appear in GDB-produced disassembly,
they may appear in some manually-generated instruction lists.
One example of such (pseudo) instruction is label.

This is the entrypoint to start VDB.
Examples:
* start VDB with no command line options/parameters
VDBStartup main: { }.
* start VDB with --no-pty command line option:
VDBStartup main: { '--no-pty' }.

applicationRegistryPath
"the key under which this application stores its process ID in the registry
as a collection of path-components.
i.e. if #('foo' 'bar' 'baz') is returned here, the current applications ID will be stored
in HKEY_CURRENT_USER\Software\foo\bar\baz\CurrentID.
(would also be used as a relative path for a temporary lock file under unix).
Used to detect if another instance of this application is already running."

This is used as the name of some exclusive OS-resource, which is used to find out,

You can paste a fresh worldwide unique id via the editor's more-misc-paste UUID menuFunction."
