An alternate would be to put the "bye" command INSIDE of the IF statement.
True, this does reduce security & may cause confusion, but it won't lock
you out [you'll be left at a command prompt if LOGON.CMD.SYS is missing]

Better still (to a degree) would be to include the logic presented in
another message to test if you are a particular user to determine if you
should be logged off when LOGON.CMD.SYS doesn't exist or if you should get
to a command prompt/recovery program [such as the command interface for
road-runner or orbit, thus allowing you to restore a copy of LOGON.CMD.SYS
from tape...]

====================
While not as secure as "option logon,nobreak" UDC's, another alternative is
to create "commands" that are menu items.  [I actually saw this done in DOS
on a PC once: someone created the files "menu.bat", "1.bat", "2.bat" and so
on -- "menu.bat" just contained echo statements, "1.bat" executed the
program for menu item 1, 2.bat for item 2, and so on]

The only real problem with this approach is that the HP cannot accept file
names or UDC's beginning with digits [does Posix support non-alpha-initial
characters?] but you can "hide" this by making what appears to be specific
purpose menus, i.e., an "administrative" menu, a "maintenance" menu,
a "report" menu, and so on -- then you can stipulate that all
admin "commands" begin with "A", maint with "M", reports with "R", and so
on.  (The "commands" become A1, A2, A3, M1, M2, R1, R2...)
