Since version 11 of Dyalog, code can be saved in UTF8 files on the hard disk. That means that you can use any utility that is able to deal with Unicode. And there are lots of them available on the net.

Here is an overview about those at least one APLer found useful:

File Comparison: CompareIt!

Especially when APL programmers are working in a team, there has to be a good comparison tool. CompareIt! turned out to be the right tool for this. More details about CompareIt!

File- and Directory Management: Total Commander

Looks, tastes and smells like the good old Norton Commander but is a fully functional Windows program. Total Commander is a great piece of software doing a much better job then the Windows Explorer. More details about Total Commander


Sending and receiving emails free, with lots of space, an excellent spam filter, a simple and easy to understand user web interface able to support even APL characters (UTF8)? Use GMail, Googles email solution. Consider to settle for the pro version: it costs little money and Google won't spy into your emails, just the NSA...

After createing an account don't forget to specify UTF-8 as the default encoding scheme (how to configure GoogleMail properly), and you can start to include APL characters into your emails without pain.. This is now the default any way.

Code Editor: Notepad++

Since UltraEdit died away due to a software desease known as featurities I settled for Notepad++ which so far is fast and handy. Let's hope that it will stay that way for some years to come.

CSS Editor: HTMLPad

My former favourite CSS editor TopStyle is any longer under development, so in late 2017 I looked for a replacement.

I found HTMLPad, and although TopStyle was really good I must admit that HTMLPad is even better. As the name suggests, it it not just a CSS editor; actually it does support several programming languages plus CSS and HTM.

Creating help files: HelpAndManual

If you want to create state-of-the-art CHM help files as well as, say, PDFs, eBooks, RTFs and web help from a single source, have a look at HelpAndManual. I am using this for 15 years now, and I was always happy with both, the product and the excellent support.


Today's cheap and large disks allow me the luxury to catch all changed files every 15 minutes with Oops!Backup in order to save the changes. It's reliable, has a simple user interface with just the right amount of options, is almost unnoticeable while running and is affordable.



An extension to the Windows context menu that allows you to get the full name of a file into the clipboard. More details about ClipboardPath

Everything is an amazing file search utility: rather than scanning the disk(s) it just reads the TOC (table of contents). That means it is lightning fast. However, it needs admin rights for this, which is kind of a security breach, so in a corporate environment you might not be able to use it.


I tried several of them over the years, some of them have been good but one is simply outstanding: SnagIt

It's actually more than just a utility to take screenshots: it can produce videos from the screen as well. This is sufficient for, say, documenting a problem or some easy steps. However, SnagIt is not designed to create long videos; they have another product for this: (Camtasia) but I have not used that (yet).

Virtual Desktops

Windows 10's built-in virtual desktops are far better than all other approaches, including SysInternal's one.
