Capitalization in Commands

Note that uppercase and lowercase letters are interchangeable in Debug commands.

The syntax shows keywords in uppercase letters.

Default Commands

Certain Debug commands have defaults. A default for a command is a variant of the

command that is executed when you simply press RETURN at the Debug prompt

without actually entering the command. Default commands are valid only when certain

conditions exist. Whenever a default command would be a valid entry, the command

name appears in the Debug prompt. For example:

251,06,00024 (FN)-

This prompt signifies that if you press RETURN, the default version of the FN

command is executed. Note that you can also enter other commands when Debug

displays this prompt.

More information about default commands is given in the descriptions of the

commands that have defaults.

Table 3-1 on page 3-2 through Table 3-5 on page 3-5, list the function or functions of

each command and give a brief description of each function.

Notation for Privileged Commands

Underlined keywords or characters in command syntax are available to privileged

users only. Keywords or characters that are not underlined are available to both

privileged and nonprivileged users.

Several Debug commands have register names as parameters or registers specified in

expressions. The form of a register specification is:

represents the contents of a processor register for that process. It can be either a

TNS/R register or a TNS environment register.

A TNS/R register is one of the following:

{ $00 | $01 | ... | $31 }

{ $HI | $LO }

{ $PC }

{ $F00 | $F01 | ... | $F31 }

{ $FCR31 }
