JF,

With regards to SYSTARTUP_VMS.COM and other command files used in the
STARTUP process, the explicit list is not correct.

The list of first level command files is stored as "phases" in files
VMS$VMS.DAT and VMS$LAYERED.DAT in directory SYS$STARTUP:[STS
$STARTUP]. SYS$STARTUP:SYSTARTUJP_VMS.COM is actually invoked one
level below that. The STARTUP databases actually may contain
additional processing required by layered products used by the files.

The only definitive way to find all files involved is to track down
the list of files contained in the STARTUP databases, and the list of
files they reference, either as data or command files, and continue
iterating until there are no new files referenced.

Therefore, any otherwise specific list will not be definitive.
