=

Performs a simple assignment.

Syntax

ares = xarg
ires = iarg
kres = karg
ires, ... = iarg, ...
kres, ... = karg, ...
table [ kval] = karg

Initialization

= (simple assignment) - Put the value of the expression iarg (karg, xarg) into the named result. This provides a means of saving an evaluated result for later use.

From version 5.13 onwards the i- and k-rate versions of assignment can take a number of outputs, and an equal or less number of inputs. If there are less the last value is repeated as necessary.

From version 5.14 values can be assigned to elements of a vector with the square bracket form.

Examples

Here is an example of the assign opcode. It uses the file assign.csd.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac     ;;;RT audio out
;-iadc    ;;;uncomment -iadc if RT audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o assign.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100
ksmps = 32
nchnls = 2

instr 1
  ; Assign a value to the variable i1.
  i1 = 1234

  ; Print the value of the i1 variable.
  print i1
endin


</CsInstruments>
<CsScore>

; Play Instrument #1 for one second.
i 1 0 1
e

</CsScore>
</CsoundSynthesizer>

Its output should include a line like this:

instr 1:  i1 = 1234.000
