Moving from 16-bit to 32-bit programming

[Petra93]

Hello, all,

For a few years I have been writing 16-bit code, using the TextPad editor, and now I would like to
get into 32-bit programming. My main interest is integer arithmetic, particularly prime numbers.

I need a recommendation for a textbook, and a recommendation for a text editor that can deal with
32-bit programs; something similar to TextPad, I suppose.

Thanks.

...As an alternative code editor, there's: JOCHEN's,  A Guide to the RichMasm Editor. JOCHEN is a very accomplished assembly language programmer, but, in all honesty, he causes my brain to hemorrhage,...
