Depends what you want to do.
Just use DOS itself or a reference with all INT21h functions to use in assembly language.

DOS for Dummies comes to mind...

Just DOS itself. Have zero experience with Assembly Language. 😅

Cool. Thanks. It looks like copies that are sold in the UK don't appear to have a front cover. It's probably one I'd have to import...?

The front cover is awesome indeed but idk if I'd import a copy just to have it. I'm sure the content within is really what you need 😀

True. I'm just not sure if the copies I'm seeing on UK Amazon and eBay are genuine though. It's hard to know for certain based on what looks like some placeholder image.

The MS-DOS 6.22 Manual is how I learned - https://ia801204.us.archive.org/33/items/msdo … _manual_622.pdf

Oh, nice. Thanks. There's loads of physical copies on eBay, too. Pretty cheap. 😁

Remember when DOS came with manuals??? I think I have my "Epson DOS 5.0" books around somewhere....
