Writing Deskshell commands

Executing actions within the same thread

The do_actions_of, do_drop_in_actions_of, do_menu_actions_of, and source commands execute the specified actions within the same thread, rather than in a separate thread.

You might want to do this to keep control over the order in which the actions are executed. For example, the following script sends the example myprint trigger, below, to a sequence of icons in the variable $*:

   for i in $*
   do
      do_actions_of myprint $i
   done

Because a do_actions_of command is used, each myprint action executes and completes before the next one is started.

NOTE: Because the action commands are executed in the same thread, changing a local variable in the trigger action for myprint will affect local variables in the current thread. Generally this is not a problem because only loop variables will be used in both scripts, and these are protected.
