At the very end of your program (every program that you write), put the code on the right. this way, when you get to the end of the program, you see the word end printed. you know that you reached the end of your program (as opposed to getting stuck in some infinite loop somewhere else, due to a bug). In this document, where the term arm is used to refer to the company it means “arm or any of its subsidiaries as appropriate”. note. the term arm is also used to refer to versions of the arm architecture, for example armv6 refers to version 6 of the arm architecture. the context makes it clear when the term is used in this way. note. The armv7 architecture is a 32 bit processor architecture. it is also a load store architecture, meaning that data processing instructions operate only on values in general purpose registers. only load and store instructions access memory. general purpose registers are also 32 bits. throughout this book, when we refer to a word, we mean 32 bits.
