Thanks very much, theoldarchiver. That is just the information I wanted.
I tried burning the 23 tracks to a 90-min disk with Toast, but Toast insisted on wanting to split them between two disks despite the CD-R being a 90-minute one, so I used Express Burn instead. That created a CD with all 23 tracks on it, which played perfectly well in iTunes and in VLC on my Mac. In my (ancient) CD player, it played continuously, but — though all 23 tracks were displayed — I was not able to select particular tracks to play. I have not had a chance yet of trying it in another, more modern, CD player.
