ControlPlayback() Plays a file, with the ability to fast forward and rewind the file
ControlPlayback(file[,skipms[,ff[,rew[,stop[,pause[,restart[,options]]]]]]])

Plays back a given file (without the file extension), while allowing the caller to move
forward and backward through the file by pressing ff and rew keys. By default, you can
use * and # to rewind and fast-forward the playback of the file, respectively.
The skipms option specifies how far forward or backward to jump in the file with each
press of ff or rew.
If stop is specified, the application will stop playback when stop is pressed.
A pause argument may also be specified, which when pressed will pause playback of
the file. Pressing pause again will continue the playback of the file.

If the restart parameter is specified, the specified key may be used to restart the play-
back of the file.
If the options parameter is set to j, and the file does not exist, the application jumps
to priority n+101, if present (where n is the current priority number).
The ControlPlayback() application sets a channel variable named CPLAYBACKSTATUS
upon completion. The CPLAYBACKSTATUS variable will be set to one of the following
values:
SUCCESS
USERSTOPPED
ERROR
; allow the caller to control the playback of this file
