Typographical Conventions

SAS/QC User's Guide uses various type styles, as explained by the following list:

  
romanis the standard type style used for most text.
  
UPPERCASE ROMANis used for SAS statements, variable names, and SAS language elements when they appear in the text. However, you can enter these elements in your own SAS code in lowercase, uppercase, or a mixture of the two. This style is also used for identifying arguments and values (in the Syntax specifications) that are literals (for example, to denote valid keywords for a specific option).
  
UPPERCASE BOLDis used in the "Syntax" section to identify SAS keywords such as the names of procedures, statements, and options.
  
italicis used for user-supplied values for options. It is also used for terms that are defined in the text, for emphasis, and for references.
  
monospaceis used to show examples of SAS statements. In most cases, this book uses lowercase type for SAS code. You can enter your own SAS code in lowercase, uppercase, or a mixture of the two. This style is also used for values of character variables when they appear in the text.
