df [count]

Move the Data Window forward count lines or one windowful if no count is given. See “Data Window Commands” on page 5-5.

dh

Display Data Window contents in hexadecimal format. See “Data Window Commands” on page 5-5.

eval expression_without_spaces+

Evaluate one or more expression_without_spaces and print the result in an appropriate format, typically hexadecimal and/or decimal, or symbolically. An expression_without_spaces can include numbers, registers, internal variables, program-defined symbols, operators, and parentheses for grouping. See “Evaluating Formulas and Formatting Data” on page 8-4.

fr

ski: Show the floating point registers in the Register Window. See “Register Window Commands” on page 5-1.

xski: Toggle the display of the floating point registers pane. See “Register Window Commands” on page 5-1.

goto label

Causes execution to continue following the first line in the file which contains the label. Goto’s may be forward or backward. Goto’s are valid only in command files. See “The goto Command and Labels” on page 9-1.

gr

ski: Show the general registers in the Register Window. See “Register Window Commands” on page 5-1.

xski: Toggle the display of the general registers pane. See “Register Window Commands” on page 5-1.

help [command_name]

Display a list of the commands Ski recognizes, or, if a command_name is specified, a syntax description for that command. See “Command Entry” on page 4-1.

iar

ski: Show the IA-32 registers in the Register Window. See “Register Window Commands” on page 5-1.

xski: Toggle the display of the IA-32 registers pane. See “Register Window Commands” on page 5-1.

iabs [address]

Set IA-32 breakpoint at address or at the current value of ip if address is omitted. (IA-32 code only) See “Setting Program Breakpoints” on page 8-4.

iaload filename address [mapfile [args]+]

Prepare for IA-32 application-mode simulation: Load an IA-32 executable file ( .com or .exe) and prepare to pass the program args using the MS-DOS command line parameter mechanism. address specifies where to load the pro- gram. mapfile provides Ski with the mapping between program-defined symbols and their addresses and must spec- ify an ASCII text file exactly compatible with mapfiles produced by the Microsoft “ML” linker. See “How to Load a Program” on page 6-3.

if expression_without_spaces true_command [: false_command]

Execute true_command if the expression_without_spaces evaluates to a non-zero value, false_command if it evalu- ates to zero. See “The if Command” on page 9-2.
