Notational Conventions

version

of the special typeface for emphasis; interactive displays use a

bold version

of the special typeface to distinguish commands that you

enter from items that the system displays (such as prompts, command
output, error messages, etc.).

Here is a sample program listing:

0011 0005 0001 .field 1, 2

0012 0005 0003 .field 3, 4

0013 0005 0006 .field 6, 3

0014 0006 .even

Here is an example of a system prompt and a command that you might
enter:

csr –a /user/ti/simuboard/utilities

In syntax descriptions, the instruction, command, or directive is in a bold
typeface font and parameters are in an

italic typeface. Portions of a syntax

that are in bold should be entered as shown; portions of a syntax that are
in

italics describe the type of information that should be entered. Here is

an example of a directive syntax:

.asect

”

section name”, address

.asect is the directive. This directive has two parameters, indicated by

sec-

tion name and address. When you use .asect, the first parameter must be
an actual section name, enclosed in double quotes; the second parameter
must be an address.

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 an instruction
that has an optional parameter:

LALK

16–bit constant [, shift]

The LALK instruction has two parameters. The first parameter,

16-bit con-

stant, is required. The second parameter, shift, is optional. As this syntax
shows, if you use the optional second parameter, you must precede it with
a comma.

Square brackets are also used as part of the pathname specification for
VMS pathnames; in this case, the brackets are actually part of the path-
name (they are not optional).

Braces ( { and } ) indicate a list. The symbol | (read as

or) separates items

within the list. Here’s an example of a list:

{ * | *+ | *– }

This provides three choices:

, or

*–
