Here is an example of a system prompt and a command that you might
enter:
C:
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
section 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 is 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
constant, 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
pathname (they are not optional).
-
Braces ( { and } ) indicate a list. The symbol | (read as or) separates items
within the list. Here is an example of a list:
{ * | *+ | *− }
This provides three choices:
*
,
*+
, or
*−
.
Unless the list is enclosed in square brackets, you must choose one item
from the list.
-
Some directives can have a varying number of parameters. For example,
the .byte directive can have up to 100 parameters. The syntax for this di-
rective is:
.byte
value
1
[, ... , value
n
]
This syntax shows that .byte must have at least one value parameter, but
you have the option of supplying additional value parameters, separated
by commas.
