CD is a program to play audio CD's on CDROM readers capable of doing so,
such as the RRD42. This version is written in C, using Motif. It requires
privilege to use (DIAGNOSE and PHY_IO), to be able to access the SCSI bus
directly.

The name may change to something more appropriate (such as CD_PLAYER). All
feedback would be quite welcome (if not absolutely necessary!). Send email
to joe@kirk.fhcrc.org or meadowsj@boeing.com with all comments.

To use the program you need to define a logical name "DECW$CD_PLAYER"
(chosen since many folks were already running the DEC CD player and have
defined this logical) to point to the name of your CD driver.

You may or may not need to set up the device to be configured manually and
configure it with the generic SCSI driver (read the beginning of CD.C for
more info on how to do that, or read DECW$EXAMPLES:DECW$CDPLAYER.C). It
appears that as early as VMS V5.4-3 (maybe earlier?) you will not need to do
this. Which means you can use it as a data drive (for bookreader or
whatever), and switch to using it to listen to music without having to do a
reboot! (many thanks to the kind souls who pointed that feature out to me).
