Notational Conventions
vi
-
Program listings and examples, interactive displays, and window contents
are shown in a special font. Some examples use a bold version to identify
code, commands, or portions of an example that
you enter. Here is an
example:
Command Result displayed in the COMMAND window
whatis aai int aai[10][5];
whatis xxx struct xxx {
int a;
int b;
int c;
int f1 : 2;
int f2 : 4;
struct xxx *f3;
int f4[10];
}
In this example, the left column identifies debugger commands that you
type in. The right column identifies the result that the debugger displays in
the display area of the COMMAND window.
-
In syntax descriptions, the instruction or command is in a bold face font,
and parameters are in
italics. Portions of a syntax that are in bold face
should be entered as shown; portions of a syntax that are in italics
describe the kind of information to be entered. Here is an example of a
command syntax:
load object filename
load is the command. This command has one required parameter, indi-
cated by
object filename.
-
Square brackets ( [ and ] ) identify an optional parameter. If you use an
optional parameter, you specify the information within the brackets; you
don’t enter the brackets themselves. Here’s an example of a command
that has an optional parameter:
run [ expression]
The RUN command has one parameter,
expression, which is optional.
-
Braces ( { and } ) indicate a list. The symbol | (read as
or) separates items
within the list. Here’s an example of a list:
sound {on | off}
This provides two choices: sound on or sound off.
Unless the list is enclosed in square brackets, you must choose one item
from the list.
