A.2.5 EXAMINE
The EXAMINE command examines the contents of the memory location or
register specified by the address. If no address is specified, + is assumed.
The display line consists of a single character address specifier, the physical
address to be examined, and the examined data.
EXAMINE uses the same qualifiers as DEPOSIT. However, the /WRONG
qualifier causes EXAMINE to ignore ECC errors on reads from physical
memory. The EXAMINE command also supports an /INSTRUCTION qualifier,
which will disassemble the instructions at the current address.
Format:
EXAMINE [qualifier-list] [address]
Qualifiers:
Data control:
/B, /W, /L, /Q, /N:{count}, /STEP:{size}, /WRONG
Address space control:
/G, /I, /M, /P, /V, /U
Command specific:
/INSTRUCTION
Disassembles and displays the VAX MACRO–32 instruction at the
specified address.
Arguments:
[{address}]
A longword address that specifies the first location to be examined.
The address can be an actual or a symbolic address. If no address is
specified, + is assumed.
