Commands and reserved words typically appear in uppercase letters. Unless you are working with Linux or the manual states otherwise, you can enter these items using uppercase, lowercase, or both. For example, you can type MYPROG, myprog, or MYprog.

Words appearing in bold include the following: menu names, dialog box names, commands, options, buttons, statements, and so forth.

Square brackets enclose optional information, as in [log_name]. If information is not enclosed in square brackets, it is required.

A vertical bar indicates a choice of information to enter, as in [file name | @file name].

Angle brackets enclose multiple choices for a required item, as in /D=<5|6|7>.

Words appearing in italics are variables that you must replace with appropriate values, as in file name.

An ellipsis following information indicates you can repeat the information more than one time, as in [parameter . . . ].

The symbol ::= means one item is defined in terms of another. For example, a::=b means the item a is defined in terms of b.
