APLTreeUtils is part of the CategoryAplTree project.
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:

Using an APLTree member
- If you just want to consume (use) an APLTree member then you have several choices:
Download it from its dedicated download page http://download.aplwiki.com/
Access it via FTP: ftp://ftp.aplwiki.com/APLTree/ with the user ID "anonymous". There is no password needed.
- Note that accessing it via ftp allows you to download older versions as well while the dedicated download page offers just the most current version.

Get the full project
If for some reason you need access to, say, the test cases then you need to get more then just the script (or application) itself.
HowToContributeToTheAPLTreeProject explains how to get a project onto your local machine. Just ignore any additional steps.
