                          Some time ago I have written a bash script which now should be able to run in environment with ash. 

In bash it was like : 

    services=( "service1.service"
               "service2.service"                                       
               "service3.service" )  
    
    for service in "${services[@]}"
    do
       START $service                   
    done

    START()
    {
       echo "Starting "$1
       systemctl start $1
    }

In reality there are like 40 services in array, and I want to make this transition as painless and clean as possible. Have always been using bashisms. Now I'm in a pinch with the task to make scripts more portable.
  
For portability reasons probably it would be nice to have a pure ash solution. But since I have a pretty robust busybox at my disposal I might sacrifice some portability. Only if readability improves a lot, since "clean" script is a metric too.  

What would be **portable** and **clean** solution in this case?
