Don: My apologies for the initial lack of info. I am also using MacOS Sierra.

I also tried running that script on my work shell.

Code:
[work@shell ~]$ ./loop.sh
./loop.sh: line 17: typeset: -n: invalid option
typeset: usage: typeset [-aAfFgilrtux] [-p] name[=value] ...

which just switches the inner and outer loops in the code I suggested before, changes the names of the arrays used as looping values, and adds code to add an empty line between groups. The above produces the output requested in post #4.
Thanks for the edit. I unfortunately do not have the option to rewrite the script my contrived example is based on from scratch. But I'll surely give ksh a try on another project! It seems to be more flexible than bash.

RudiC: Here is the code with typeset -n that I wasn't lucky with:

Code:
#!/bin/sh

declare -a index=(0 1 2 3 4);

declare -a animals=(dog cat horse penguin cow);

declare -a fruits=(orange apple grapes peach mango);

declare -a drinks=(juice milk coffee tea coke);

declare -a cities=(toronto paris london glasgow sydney);

declare -a countries=(canada france england scotland australia);

declare -a all=(animals fruits drinks cities countries);

typeset -n j

for i in "${index[@]}" ; do
  echo ${i};
  for j in "${all[@]}" ; do
    echo ${!j}, ${j[$i]};
  done;
done

It looks like neither shell at home or work has typeset -n Smilie
