RE: Term for language that abstracts program location?

I’m thinking here specifically of the evolution of HP keystroke languages, from early (and some late) models where each instruction exists in a single linear space (e.g., before the 41 series), to (some) later models such as the 41 series and the 42S, where each program exists in its own space.

Is there a formal term for this difference?

(Note that I’m thinking here exclusively of cases like the examples given, where the languages used are otherwise the same, and not of more comprehensive changes in system architecture, for which this change comes as part of the package — e.g., RPL.)

Bonus question: What other (non-RPL) models have this feature, aside from the 41 family and the 42S?

I think high level language" was widely used for the languages that came after assemblers. But that doesn't seem like the distinction you're talking about.

Of the languages I know, APL seems the earliest (1967) "language" which had sense of workspaces and functions.
