Well if you consult the bible Structure and Interpretation of Computer Programs
by Abelson, Sussman, and Sussman, the term function is strictly reserved for
mathematical objects, and procedure is uniformly used for what people loosely
call functions.
As to the discussion about the distinction b
Pascal, as many other languages, has its roots in Algol 60.
In the latter, there was only the « procedure » keyword.
You just prefixed the definition with a type to make it a function, such as:
integer procedure foo (…)
begin
…
foo := …;

Hi all,

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
