Console Commands 3-21

Examine uses most of the same options as deposit. Additionally, the ex-

amine command supports the -d option (instruction decode, which will

disassemble the instructions at the current address). When using exam-

ine, if no options are given in subsequent commands, the system uses the

options from the preceding commands as the defaults for address or loca-

tion referenced, data type, including -d, (-b, -l, -w, and so forth), data size

for increment (-s), and address space (gpr, ipr, pmem, and so forth).

After initialization, the default address space is physical memory, the de-

fault data size is a longword, the default address is zero, and the default

address increment size is the data size. If conflicting address space or data

sizes are specified, the console ignores the command and issues an error

response.

Table 3-5 Device Name and Address Space Options

Option Device Name and Address Space Meaning

<dev_name>

Device name: xmi0, ka7aa1, demna0, and so forth.

fpr

Defines the address space as the floating-point register

set, F0 through F31 (DEC 7000 only).

gpr

Defines the address space as the general register set,

R0 through R15. The data size is always a longword.

ipr

Defines the address space as the internal processor

registers (IPRs). The data size is always a longword.

Defines the address space as the PAL temp register

set, PT0 through PT31 (DEC 7000 only).

pmem

Defines the address space as physical memory.

vmem

Defines the address space as virtual memory. All ac-

cess and protection checking occur.
