How to play a music with tone?

[胡松涛]

Hi everyone,

I want to make a small demo for Open Firmware to show that it can play a  
music.
the very basic is : play, pause, play
with play, I use tone . but, I can't find WORD for pause, where is it?

further more, I read some articles about midi file. It's a little  
complicated for me. So I want to finished the first tone-music first :)

PS: Are there some detail articles about Open Firmware handle with music?  
wav, midi, mp3 or event avi?

For pause, do you mean a time delay?  If so, you can use

ms  ( #msecs -- )

For example

d# 1000 ms

will delay for 1 second.

OFW can play .wav files - see cpu/x86/adpcm.fth .

OFW does not have any built-in support for midi or mp3.  Midi playback 
requires sound synthesis code or a hardware sound synthesizer.  mp3 
playback requires a patent license from Fraunhofer so I cannot include 
that capability in free software.

I'm not sure what you mean by "event avi".
