No question that DCL was there from day one of VMS. That does not mean 
DCL didn't exist before VMS.

Desperately seeking for the source/reference now, but failing at the 
moment (I'll find it sooner or later). But thinking about it, I'm fairly 
sure DCL originated on IAS.

Ah - found one (it). https://www.john-a-harper.com/ias.html (by one of 
the people working on/implementing IAS.)

DCL for sure already existed by -11M 3.2, though.

Looking at RSX sources would date that version to 1980.

RSTS/E DCL is way later. But it is maybe the one closest to VMS.

TOPS-20 EXEC is (as others mentioned) nothing near DCL.
