Conventions used

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

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "A string parameter value is present in a string list."

A block of code is set as follows:

function IsPresentInList(strings: TStrings; const value: string): Boolean;
var
  i: Integer;
begin
  Result := False;
  for i := 0 to strings.Count - 1 do 
    if SameText(strings[i], value) then 
      Exit(True);
end;

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Go to Options | Options, then select General | Search directory."
