Debugger Command Syntax - Motorola MVME167 Series Installation Manual

For example, if a breakpoint has been specified, then control returns
to the debugger when the breakpoint is encountered during
execution of the user program. Alternately, the user program could
return to the debugger by means of the TRAP #15 function
".RETURN".

Debugger Command Syntax

In general, a debugger command is made up of the following parts:
The commands are shown using a modified Backus-Naur form
syntax. The metasymbols used are:
boldface strings
italic strings
|
[ ]
{ }
The command identifier (i.e., MD or md for the Memory
Display command). Note that either upper- or lowercase is
allowed.
A port number if the command is set up to work with more
than one port.
At least one intervening space before the first argument.
Any required arguments, as specified by the command.
An option field, set off by a semicolon (;) to specify conditions
other than the default conditions of the command.
A boldface string is a literal such as a command or a
program name, and is to be typed just as it appears.
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.
