The commands are shown using a modified Backus-Naur form syntax. The metasymbols used are: boldface strings A boldface string is a literal such as a command or a program name, and is to be typed just as it appears. italic strings An italic string is a “syntactic variable” and is to be replaced by one of a class of items it represents. | A vertical bar separating two or more items indicates that a choice is to be made; only one of the items separated by this symbol should be selected. [ ] Square brackets enclose an item that is optional. The item may appear zero or one time. { } Braces enclose an optional symbol that may occur zero or more times.Syntactic Variables The syntactic variables shown below are encountered in the command descriptions on the following pages. In addition, other syntactic variables may be used and are defined in the particular command description in which they occur.del Delimiter; either a comma or a space. exp Expression (described in detail in a following section). addr Address (described in detail in a following section). count Count; the syntax is the same as for exp. range A range of memory addresses which may be specified either by addr del addr or by addr: count. text An ASCII string of up to 255 characters, delimited at each end by the single quote mark
