playdone

#playdone

##Syntax playdone : boolean

##Description The playdone function is used to determine when notes played by the play procedure have finished sounding.

##Example This program sounds the first three notes of the C scale and outputs "All done" as soon as they are finished. Without the loop, the message would come out before the notes are finished.

    play ( "cde" )
    loop
        exit when playdone
    end loop
    put "All done"

##Details Under some systems such as UNIX, the playdone procedure may be meaningless.

##See also the play.html procedure.html. See also the sound.html procedure.html which makes a sound.html of a given frequency (Hertz) and duration (milliseconds).
