## print

print — Displays the values init (i-rate) variables.

## Description

These units will print orchestra init-values.

## Syntax

    print iarg [, iarg1] [, iarg2] [...]

## Initialization

iarg, iarg2, ... -- i-rate arguments.

## Performance

print -- print the current value of the i-time arguments (or expressions) iarg at every i-pass through the instrument.

| Note
The print opcode will truncate decimal places and may not show the complete value. Csound's precision depends on whether it is the floats (32-bit) or double (64-bit) version, since most internal calculations use one of these formats. If you need more resolution in the console output, you can try printf.

## Examples

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

Example 380. Example of the print 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
    ; Audio out   Audio in
    -odac           -iadc    ;;;RT audio I/O
    ; For Non-realtime ouput leave only the line below:
    ; -o print.wav -W ;;; for file output any platform
    </CsOptions>
    <CsInstruments>

    ; Initialize the global variables.
    sr = 44100
    kr = 4410
    ksmps = 10
    nchnls = 1

    ; Instrument #1.
    instr 1
      ; Print the fourth p-field.
      print p4
    endin

    </CsInstruments>
    <CsScore>

    ; p4 = value to be printed.
    ; Play Instrument #1 for one second, p4 = 50.375.
    i 1 0 1 50.375
    ; Play Instrument #1 for one second, p4 = 300.
    i 1 1 1 300
    ; Play Instrument #1 for one second, p4 = -999.
    i 1 2 1 -999
    e

    </CsScore>
    </CsoundSynthesizer>

Its output should include lines like this:

    instr 1:  p4 = 50.375
    instr 1:  p4 = 300.000
    instr 1:  p4 = -999.000
