VMS did not exist 40 years ago.

But within the obvious limitation of the same instruction set, then
I would expect VMS programs to also continue to run forever.

Meaning that a VMS VAX 1.0 program from 1978 should run today
VMS VAX 7.3 and a VMS Alpha 1.0 (before version number
synchronization was done) program from 1992 should run today on
VMS Alpha 8.3.
