Instruction manual

After initialization, the default address space is physical memory, the default
data size is a longword, and the default address is 0. If conflicting address space
or data sizes are specified, the console ignores the command and issues an error
message.
Options/Qualifiers
address
access size options
-b Byte data size
-w Word data size
-l Longword data size
-q Quadword data size
address options
-pm The address space is physical memory.
-vm The address space is virtual memory. All access and protection checking occur. If
the access would not be allowed to a program running with the current PSL, the
console issues an error message. Virtual space DEPOSIT commands set the PTE
M bit. If memory mapping is not enabled, virtual addresses are equal to physical
addresses.
miscellaneous options
-u Access to console private memory is allowed. This option also disables virtual
address protection checks. On virtual address writes, the PTE M bit is not set
if this option is present. This option is not inherited and must be respecified on
each command. This must also be used when accessing I/O space not mapped
by the console.
-n val Specifies the number of consecutive locations to read. The console reads the
first address, then to the specified number of succeeding addresses.
-s val Specifies the address increment size. Normally this defaults to the data size,
but is overriden by the presence of this option. This option is not inherited.
display options
-a Interpret the data as ASCII data and display as such. Non-printing characters are
displayed as a period (.).
In the absence of an access or address option, the previous option is used.
Specification of conflicting options is an error; the command is ignored and an
appropriate error message is displayed.
address
* The location last referenced in an EXAMINE or DEPOSIT command.
+ The location immediately following the last location referenced in an EXAMINE
or DEPOSIT command. For references to physical or virtual memory spaces, the
location referenced is the last address, plus the size of the last reference (1 for
byte, 2 for word, 4 for longword).
- The location immediately preceding the last location referenced in an examine
or deposit. For references to physical or virtual memory spaces, the location
referenced is the last address, minus the size of the last reference (1 for byte, 2 for
word, 4 for longword).
