Especially since Pascal was the first place that I was exposed to
different kinds of calling conventions, I've been waiting for this
thread to mention some version of the Niklaus Wirth joke:

Oops, I have to reply to myself. Matthew correctly reminded me that it is
call-by-value/pass-by-worth
what I mean for Racket and Java not .../pass-by-reference. Sorry for the
confusion.

Thank U very much,
Our project is about "programming language principle". during the semester
we have been programming a compiler for Jack language in racket,
and now we need to make a presentation on Racket language that includes all
information about the principle that we learned.

I apologize for spreading this nonsense. Is it the phrase "reductio
call-by is a notion of time, pass-by refers to entity that is used (location if
you so will). You can create a 2-dimension table of these options and you'll be
able to find some language for almost any cell in this table.
The common meaning of call-by-value is call-by-value/pass-by-reference.

I suspect two different things are being conflated here:
1. the reduction semantics of the language
2. t
Be aware there is also a lazy racket (#lang lazy)
#lang racket ; call by value
(define (show x) (display x) (newline) x)
(define (plus x y z)
(display "now we are in the procedure\n")
(+ x y z))
"the procedure has been defined"
(plus (show 1) (show 2) (show 3) )
"the proceedure has been calle
thank u :)
but we didn't understand if the arguments are passed by value or reference?
we think that it passed by value, and if we use with pointers it can pass
by refernce.
another question,
if we use let function, the argument is passed by name?
thank u very much!

See section 4.3.1 of the Racket guide.
