How to display Help Files from APL

ShowChmHelp is part of the CategoryAplTree project.


This class serves two simple purposes:

You must create an instance before you can use the methods the class is coming with, and you must make sure that the Destructor is called at some point because otherwise APL might crash. This is neither a fault of the class nor of APL, it's simply how the underlying DLL is defined.

You can get details about how to use ShowChmHelp with the ADOC user command; execute:

    ]ADOC #.ShowChmHelp

Using an APLTree member

  1. If you just want to consume (use) an APLTree member then you have several choices:

* Access it via FTP: 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.
  • Download any release since the conversion to GitHub (2018-02) from GitHub. You can compile the URL by{name}


If you want to contribute to an APLTree project see HowToContributeToTheAPLTreeProject for details.

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.
