Basic Alpha SRM Console Command Descriptions

examine Command Option

Description

-ipr

References internal processor register address space.

-n<count>

Specifies the number of consecutive locations to

 

examine.

-s<step>

Specifies the address increment as a hexadecimal value.

 

This option allows you to override the increment that is

 

normally derived from the data size.

 

 

Description

The examine command displays the contents of the specified address, such as a memory location, register, device, or file. The defaults for address space, data size, and address are the last specified values. After initialization, the default for address space is physical memory; for data size, the default is a quadword; and for address, the default is zero.

An address or device can be specified by concatenating the device name with the address. For example, use pmem:0 and specify the size of the address space to be displayed. If a conflicting device, address, or data size is specified, the console ignores the command and issues an error response.

The display line consists of the device name, the hexadecimal address (or offset within the device), and the examined data (also in hexadecimal).

The examine command supports the same options as the deposit command. Additionally, the examine command supports instruction decoding with the -doption, which disassembles instructions beginning at the current address.
