What language coined the term lvalue? [closed]

Question

Was C the first programming language to use the term lvalue, or does it go further back? Note that I'm not talking about the general concept of "something on the left-hand side of an assignment statement" (which it has ceased to mean in C++ a long time ago). You can find that in pretty much any imperative programming language. I am specifically asking about the term lvalue. Where does it come from?

Answer 1
