variable number of checkboxes in dialog

I am using Cdparanoia and Sox (play) to play CD's on an old Nokia internet tablet. I am using 'dialog' with the checklist option, to either select individual tracks or the entire disk for playback.

How can I adapt the script so that it can find out the number of tracks on the CD and so create a checkbox for each track (and name them track1, track2 etc)

I can find the number of tracks:

var=`cdparanoia -sQ |& cat | wc -l`; echo $[ $var - 8 ]

and the script that I am currently using is based on:

 #!/bin/bash

 mycmd=(dialog --separate-output --checklist "Select options:" 22 76 16)
 options=(1 "Track 1" off # any option can be set to default to "on"
 2 "Track 2" off
 3 "Track 3" off
 4 "All Tracks" off)
 choices=$("$mycmd[@]" "$options[@]" 2>&1 >/dev/tty)
 clear
 for choice in $choices
 do
 case $choice in
 1)
 echo "Track1"
 ;;
 2)
 echo "track2"
 ;;
 3)
 echo "track3"
 ;;
 4)
 echo "All Tracks"
 ;;

Actually that's not a checklist, but a menu (see the manual). As a start, you'd have to add a column to the array of off tokens.
