Predetermined? Eventually.

While dibbling around looking at how the singularity module is built I wondered about altering it.
Of course this rather means I need to understand how it works and how to write a module.
So, knowing I have the odd book around I look and fail to find anything relevant.

Then today I find a reference to an old text: the dabhand guide to the archimedes OS. Certain I’d seen it before I looked and found it.

It had a bookmark, of my normal style ¹ marking page 123, the start of Chapter 11: Writing modules.
What stopped me reading the text back then? Well, the sheet is for a photographic firm in Cradley Heath. I know of only one instance I used the services of a professional photographer.²
Bit of light reading ahead, and a bit of translation of the 26 bit-isms I find, unless I get allocated a different task…

¹ A bit of paper or a single sheet of advertising literature, these are handy because you can mark a second page by tearing the bookmark in two.
² My distraction is out tonight.
