User guide

An alternate method for dumping memory (or other devices or files) is the hex
dump command, hd. The -l option specifies the number of bytes to display.
Note
Both -l and -n have the same result, but -l only works with hd and -n
only works with examine. The distinction is caused by the commands;
examine is a VMS like command and hd is a UNIX cloned command.
>>> hd pmem:3fff000 -l 10 # Dump the allocated memory.

12.4.2 Examining Registers
You can use the examine and deposit commands to refer to registers. You must
include the address for the registers in one of the following ways:
• Symbolically, for example, r0 or ksp
• Explicitly, as offsets within device address space, for example, gpr:0 or ipr:0
• Implicitly, as offsets within the current device address space, for example, 0
You can also use the symbolic addresses +, *, -, and the implied address increment
(no address specified). The following examples show the ways to include an
address, as described in each command’s comment.
