In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows:

"If you decide to move it elsewhere, do not forget to put the INCLUDE folder and the FASMW.INI file (if one has already been created) into the same directory."

A block of code is set as follows:

fld     [radius]    ; Load radius to ST0
                    ; ST0 <== 0.2345
fldpi               ; Load PI to ST0
                    ; ST1 <== ST0
                    ; ST0 <== 3.1415926
fmulp               ; Multiply (ST0 * ST1) and pop
                    ; ST0 = 0.7367034
fadd    st0, st0    ; * 2
                    ; ST0 = 1.4734069
fstp    [result]    ; Store result
                    ; result <== ST0

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

sudo yum install binutils gcc

New terms and important words are shown in bold.
