Typographical Conventions

The printed version of SAS/OR User's Guide: Mathematical Programming uses various type styles, as explained by the following list:


roman	is the standard type style used for most text.

UPPERCASE ROMAN	is used for SAS statements, options, and other 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 BOLD	is used in the "Syntax" section to identify SAS keywords, such as the names of procedures, statements, and options.

bold	is used in the "Syntax" section to identify options.

helvetica	is used for the names of SAS variables and data sets when they appear in the text.

oblique	is used for user-supplied values for options (for example, VARSELECT= rule).

italic	is used for terms that are defined in the text, for emphasis, and for references to publications.

`monospace`	is 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.
