the parent page has pointers to additional resources. Medley Interlisp also includes an online reference:
- right-click on the desktop to get to the system menu
- select DInfo
or, at any prompt, the man
command will look up a symbol or phrase in the Interlisp Reference Manual (IRM) and/or the Common Lisp HyperSpec.
In an (INTERLISP) Exec window, type the following:
(PLUS 1 1)
When you complete typing the ending )
the Interlisp interpreter will perform the calculation and return the result.
One thing you probably noticed, the function name PLUS
is capitalized. This is traditional -- Interlisp programmers commonly ran with the caps-lock turned on. It’s not that the developers of Interlisp were always shouting at each other. Rather, when Interlisp was developed computer programming was in its early days and all-caps type-in was common. (It's possible to change the Interlisp exec to automatically capitalize symbols at input, as is the case with the Common Lisp exec, if that's your preference.)
