VMS goes back to the 70's, now across 4 architectures: VAX, Alpha, Itanium, and now x86. I'm sure it has accumulated a ton of cruft for backwards compatibility.

VMS goes back to the 70's, now across 4 architectures: VAX, Alpha, Itanium, and now x86. I'm sure it has accumulated a ton of cruft for backwards compatibility. I worked at a VMS shop for a bit during college and shortly thereafter! It's fun to play around with, but nothing I'd want to deal with full time.
