A Command Reference
In the command descriptions that follow, this face indicates literal text you should type, this face indicates operand text
you should modify, [bracketed text] indicates text you may choose to omit (never type the brackets), and the + symbol
indicates items you may repeat. The syntax of the command language is described in Chapter 4, “Command Language”.
The order in which commands appear here is the order in which they may be abbreviated: any command may be abbrevi-
ated to as few letters as are needed to distinguish it from all commands preceding it in the list below. For example, the
“step” command may be spelled out in full or abbreviated as “ste”, “st”, or “s”. The “save” command can be spelled
out in full or abbreviated as “sav” or “sa”. It can’t be abbreviated as “s” because it follows “step” in the list below.
. filename
Execute commands from the command file specified by filename. The file is opened and its contents are executed as
if they were entered from the keyboard. When the contents are exhausted,
ski
and
xski
resume reading commands
from the keyboard.
bski
, on the other hand, executes a run command and then a quit command (unless, of course,
the command file already executed a quit command). Command files can be nested to a reasonable level. See Chap-
ter 9, “Command Files”.
# comment
Comments may be used to help document the design and implementation of command files. A comment is any part
of a line following an octothorpe (“#”). The octothorpe and everything following it on the line are ignored. See
“Comments in Command Files” on page 9-2.
label:
Labels are targets for goto commands and are valid only in command files. See “Labels and Control Flow in Com-
mand Files” on page 9-1.
= register_name value
Assign value to the register specified by register_name. Unless a modifying prefix such as 0d, 0o,or0b is used,
value will be treated as a hexadecimal number. See “Changing Registers and Memory with Assignment Commands”
on page 8-1. The register names recognized by Ski are listed in “IA-64 Registers” on page B-1.
=1 address value+
=2 address value+
=4 address value+
=8 address value+
The value is assigned to the specified location in memory. The old value at the location is lost. The location may be
on any allocated page, including instruction pages. Multiple values separated by whitespace may be supplied; if so,
they will be assigned to sequential memory addresses. Unless a modifying prefix such as 0d, 0o,or0b is used, value
will be treated as a hexadecimal number. See “Changing Registers and Memory with Assignment Commands” on
page 8-1.
The =1 command truncates any extra high-order bytes of the value to make a single byte. The =2 command truncates
or pads (with zero) the high order bytes of the value as necessary to make a two-byte quantity. Similarly, the =4 and
=8 commands truncate or pad high order bytes to make four- and eight-byte quantities, respectively. The psr.be bit
controls whether the data is stored in big-endian or little-endian format.
=s address string_without_spaces
The string_without_spaces is assigned to memory locations starting at the location specified by address. A null byte
is added to the end of the string automatically. The old value at the location is lost. The location may be on any allo-
