## =

= — Performs a simple assignment.

## Syntax

    ares = xarg

    ires = iarg

    kres = karg

    ires, ... = iarg, ...

    kres, ... = karg, ...

## Description

Performs a simple assignment.

## 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.

## Examples

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

Example 25. Example of the assign opcode.

See the sections Real-time Audio and Command Line Flags for more information on using command line flags.

    <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
