OK, now I realize what people are saying -- the menus in UCSD Pascal were not "drop-down." Sorry, I'm so used to letting the term trip from my fingers that I mistyped.
Yes, they were single letter menu commands on a character-based "graphic" screen.
They did influence the development of drop-down menus at Apple.

I have 8" floppy media for UCSD Pascal that runs on my MINC-11; I have
not attempted to run it on other PDP-11s yet. It behaves as Al
describes. -- Ian
