APLTreeUtils

APLTreeUtils is part of the CategoryAplTree project.

Many classes in the APLTree project (with the notable exception of ADOC which is self-content) :Include the namespace script APLTreeUtils.

That means that before you can load successfully one of these classes you must make sure that the namespace script #.APLTreeUtils is already in the current workspace. (If you use ScriptManager it will deal with that for you)

Note that all functions in APLTreeUtils are independent from ⎕IO as well as ⎕ML.

Although APLTreeUtils is designed to be included in classes there is nothing wrong with calling its functions from outside like this:

      APLTreeUtils.FindPath
