USUAL-OPSYS="note" NOTE-START The vax (-machine=vax) runs zillions of different operating systems. Vax running Berkeley Unix (-opsystem=bsd4-1, -opsystem=bsd4-2 or -opsystem=bsd4-3) Works. Vax running Ultrix (-opsystem=bsd4-2) Works. See under Ultrix in share-lib/MACHINES for problems using X windows on Ultrix. Vax running System V rel 2 (-opsystem=usg5-2) 18.27 Works. Vax running System V rel 0 (-opsystem=usg5-0) Works as of 18.36. Vax running VMS (-opsystem=vms) 18.36 believed to work. Addition of features is necessary to make this Emacs version more usable.
