For a more complete set of basic examples please see the distributed source code. Vuza uses the classic prefix notation typical of Lisp/Scheme:
(+ 1 2 (- 3 5)) 
The classic "Hallo world!" program is:
(begin (display "Hallo world!") (newline))
It is possible to define functions with the Lambda operator:
(define twice (lambda (x) (+ x x )))
It supports a powerful macro-system similar to Lisp, based on quotations and quasiquotations:
(define ignore (macro (x) `(quote ,x)))
It can operate on high-order functions:
(map (lambda (x) (+ x 2)) '(1 2 3 4))


Bindings (Csound and FLTK)

The following example shows, the integration of some Csound code into vuza:
	(load "vuzcsnd.scm")

	(csound-initialize CSOUNDINIT_NO_ATEXIT)
	(define cs (csound-create))
	(define orc "sr=44100\nksmps=32\nnchnls=2\n0dbfs=1\n\ninstr 1\naout vco2 0.5, 440\nouts aout, aout\nendin")
	(define sco "i1 0 1")
	(csound-send cs 'set-option "-odac")
	(csound-send cs 'compile-orc orc)
	(csound-send cs 'read-score sco)
	(csound-send cs 'start)
	(csound-send cs 'perform)
	(csound-destroy cs)
The following example shows how to create a simple UI and assign actions to the created controls by means of a callback lambda function:
	(load "vuztk.scm")
	(define window (fl-make-widget 'window 0 0 395 180 "FLTK"))

	(define slider1 (fl-make-widget 'hor-value-slider 5 5 380 30 "Sl1"))
	(define slider2 (fl-make-widget 'hor-value-slider 5 65 380 30 "Sl2"))
	(define slider3 (fl-make-widget 'hor-fill-slider 5 125 380 30 "(Sl3 - connected to Sl1)"))
	(fl-send slider3 'set_output)
	(define (cback1 caller) 
		(define v (fl-send caller 'value))
		(display "Sl1 value = ") (display v) (newline)
		(fl-send slider3 'value! v))
	(define (cback2 caller) 
		(define v (fl-send caller 'value))
		(display "Sl2 value = ") (display v) (newline))
	(fl-send slider1 'callback cback1)
	(fl-send slider2 'callback cback2)
	(fl-send slider3 'color 127)
	(fl-send window 'end)
	(fl-send window 'show)
