## flashtxt

flashtxt — Allows text to be displayed from instruments like sliders

## Description

Allows text to be displayed from instruments like sliders etc. (only on Unix and Windows at present)

## Syntax

    flashtxt  iwhich, String

## Initialization

iwhich -- the number of the window.

String -- the string to be displayed.

## Performance

Note that this opcode is not available on Windows due to the implimentation of pipes on that system

A window is created, identified by the iwhich argument, with the text string displayed. If the text is replaced by a number then the window id deleted. Note that the text windows are globally numbered so different instruments can change the text, and the window survives the instance of the instrument.

## Examples

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