cated page, including instruction pages. Multiple values may not be supplied. The string may not contain spaces and quoting it is not a workaround. See “Changing Registers and Memory with Assignment Commands” on page 8-1.

bs [address]

Set breakpoint at the location specified by the current value of ip or at the specified address. (IA-64 code only) See “Setting Program Breakpoints” on page 8-4.

bD

Delete all breakpoints. See “Deleting Program Breakpoints” on page 8-5.

bd breakpoint_number

Delete breakpoint breakpoint_number. Use the bl command to get a list of all breakpoints and their corresponding numbers. See “Deleting Program Breakpoints” on page 8-5.

bl

Display a list of current breakpoints. See “Listing Program Breakpoints” on page 8-5.

cont

Continue simulating the program from the current ip value. Most commonly used after the simulator stops at a breakpoint. See “Program Execution” on page 6-5.

dj [address]

Jump the Data Window display to the specified address. If no address is given, the window display changes to the previous location, providing a handy way to swap the display between two different parts of memory. See “Data Window Commands” on page 5-5.

db [count]

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

dbndl

Display the Data Window contents as instruction bundles. See “Data Window Commands” on page 5-5.

dbs address length [rwrw]

Set data breakpoint covering the memory area of length bytes starting at address. See “Setting Data Breakpoints” on page 8-7.

dbD

Delete all data breakpoints. See “Deleting Program Breakpoints” on page 8-5.

dbd breakpoint_number

Delete data breakpoint breakpoint_number. Use the dbl command to get a list of all breakpoints and their corre- sponding numbers. See “Deleting Program Breakpoints” on page 8-5.

dbl

Display a list of current data breakpoints. See “Listing Program Breakpoints” on page 8-5.

ddstarting_address ending_address [filename ]

Dump memory contents to the screen or to the file given by filename . The range dumped is between starting_address and ending_address inclusive. The dump is formatted as hexadecimal. See “Data Window Commands” on page 5-5.
