Re: "procedure" vs. "function"

[Jacques Menu]

Hello,

Yes, historically a disctinction was made between the « sub-programs » that return a value and those that don’t, but the Scheme docs seem to use the terms function and procedure interchangeably.

In C++, everything is a function : a procedure is merely a function that returns a value of the « void » type, i.e. no value.

Hi all,

I just stumbled over a terminology issue: are "procedure" and "function" synonyms in Scheme or do they refer to different things?

From my earliest experiences with programming I'd recall the difference to be that functions return a value and procedures don't. But that's clearly not the case in Scheme.

Any enlightenment available?

Well, I'm guilty of using them interchangeably...

Anyway, maybe the following will help -- or add to the confusion :)
