Conventions

In this book, you will find a number of styles of text 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: " This recipe uses the cup98lrn reduced vars2.txt data set."

A block of code is set as follows:

if length(s) < 3 then '0'
elseif member(s(3),[B P F V]) and c2 /= '1' then '1'
elseif member(s(3),[C S K G J Q X Z]) and c2 /= '2' then '2'
elseif member(s(3),[D T]) and c2 /= '3' then '3'
elseif s(3) = 'L' and c2 /= '4' then '4'
elseif member(s(3),[M N]) and c2 /= '5' then '5'
elseif s(3) = 'R' and c2 /= '6' then '6'
else '' endif

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "clicking the Next button moves you to the next screen".
