I'm not Tom, but I'm quite sure that was Version 1 Release 2 Modification
Level 0. As others have noted, "You can't have a Release 0".

This is all muddied by inconsistency in including the Version number. VM,
for instance, had VM/XA 1.0 and VM/ESA 1.0 (among others) because the
"Version 1" was implicit (or not even thought of, perhaps).

Product versioning is arcane and varies across vendors and even within
vendors; some folks think 2.9.13b is somehow more useful/meaningful than
just going to 2.9.14. I don't, but that's me.
