Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Subtraction using the SBC instruction tends to be a bit more confusing to novice 6502 assembly language programmers."

A block of code is set as follows:

; Add four bytes together using immediate addressing mode
LDA #$04
CLC
ADC #$03
ADC #$02
ADC #$01

Any command-line input or output is written as follows:

C:\>bcdedit
Windows Boot Manager
--------------------
identifier              {bootmgr}

Bold: Indicates a new term, an important word, or words that you see onscreen. Here is an example: "Because there are now four sets, the Set field in the physical address reduces to two bits and the Tag field increases to 24 bits."
