This is such a simple question, but I can't find an answer in the manual.
How do I, under program control, create an empty list, or else initialize an existing list (of arbitrary size) to empty? I know how to do it from the keyboard by going into the VAR menu, selecting the list, and pressing [DEL]. (By "program" I mean HP-BASIC, not SysRPL.)
I'm trying to get a program to initialize itself to a known state, which requires an empty list to which it can add things as it goes.
