To read a 16-bit value, you add ^^r, alias the little rad symbol

That's just a way to write the symbol without having it in the keyboard. We just replaced the character for this trio. It's just a convention.

Yay, finally a question in my area of expertise  

By {e9830}^^r he means {E9830}r (note the E is the same E used with scientific location and the r is the r located under the degree menu), which is the beginning of the VAT. {E982E}r is the end (second E is a normal E). When you don't have the r at the end it will not work.

But the problem I found with AMEMKIT was that it does not display hidden programs.
I used this method to make my own Axe library that I used in AlphaCS that will find the program names in alphabetical order and return information such as if the program is archived, hidden or locked. If you're interested I'll post the updated version here for you to use.

Cool, an on-calc IDE for Axe programs? There are multiple people including me that are working on one right now, good luck  it's really hard though, I keep getting stuck.
