Unlike DECnet, the LAT subsystem doesn't have a permanent database so LAT changes must be made in file "SYS$MANAGER:LAT$SYSTARTUP.COM"
On system startup OpenVMS will always process file "SYS$MANAGER:SYSTARTUP_VMS.COM". A LAT-based print-queue requires that both the QUEUE/MANAGER and LAT be running so it's always a good idea to add some code to recreate your print queue near the end of "SYSTARTUP_VMS.COM" (in a place after both the QUEUE/MANAGER and LAT are started). Be sure to do a "SET NOON" before your modifications so the system will ignore typos.
