This program allows interaction with a CD-ROM drive to select a range of sound to play, and generate the text for a CDPlay command to be used when the button is pressed.
From the dialog, input selection is by track or absolute time location on the audio CD. TIME values may be adjusted using the POSITION SELECT slider. Start and end of play are established by selecting SET START and SET END. Player control parameters are entered from the OPTIONS dialog. TRYIT will exercise selected time values. Use KEEP to retain values for your new button.

For HyperLogo calls, the command string should begine with a blank (entered as '\ '), and the '+' character must be set using the HyperLogo construct '\+'.
On some Macintosh models, it may be necessary to manually set the sound input source to Internal CD, before using CDPlay. This is also true when CDPlay is used with a non-U.S. version of the Mac OS.
