Can lists and subroutine handlers mix?

[Ray_Barber]

I have been trying to store subroutine handlers in a list, without calling the subroutines when the list is set.
There ia an old Mac Observer article stating that this used to be possible.
Mac Observer subroutine article

on check_triggerList for posKey
set triggerList to {“test1”, “test2”, “test3”, “test4”} –list of possible triggers
set routineList to {routine1, routine2, routine3, routine4} –subroutine calls

 [b][color=blue]repeat[/color][/b] [b][color=blue]with[/color][/b] [color=green]t[/color] [b][color=blue]from[/color][/b] 1 [b][color=blue]to[/color][/b] [b][color=blue]the[/color][/b] [color=blue]count[/color] [b][color=blue]of[/color][/b] [color=green]triggerList[/color] --[i][color=olive]goes through the triggerList to find a reference number[/color][/i]
      [b][color=blue]if[/color][/b] [color=blue]item[/color] [color=green]t[/color] [b][color=blue]of[/color][/b] [color=green]triggerList[/color] [b][color=blue]is[/color][/b] [color=green]posKey[/color] [b][color=blue]then[/color][/b]
           [b][color=blue]set[/color][/b] [color=green]new_routine[/color] [b][color=blue]to[/color][/b] [color=blue]item[/color] [color=green]t[/color] [b][color=blue]of[/color][/b] [color=green]routineList[/color]
           [color=green]new_routine[/color]()
      [b][color=blue]end[/color][/b] [b][color=blue]if[/color][/b]
 [b][color=blue]end[/color][/b] [b][color=blue]repeat[/color][/b]

end check_triggerList

It seems that this code should work, but it does not.
I would be grateful if someone could offer a suggestion as to how I could make something along these lines work.

Thanks

You have the right principle, but the variables you use to access the handlers have to be globals.

on check_triggerList for posKey

  global routine1, routine2, routine3, routine 4, new_routine
  
  set triggerList to {"test1", "test2", "test3", "test4"} --list of possible triggers
  set routineList to {routine1, routine2, routine3, routine4} --subroutine calls

  repeat with t from 1 to the count of triggerList --goes through the triggerList to find a reference number
    if item t of triggerList is posKey then
      set new_routine to item t of routineList
      new_routine()
    end if
  end repeat

end check_triggerList

That worked great. Gave me a bit of trouble because I had not noticed that you had made new_routine a global as well.
My lack of attention to detail will be the death of me some day.

Thanks again.
