Address Syntax
Address Syntax
Many Debug commands require you to specify an address. The syntax for an address
is as follows:
32-bit-address
defines the 32-bit address where the code or data is located.
TNS-style
defines the code or data segment address for TNS users. The syntax for the TNS-
style address is as follows:
address-mode
defines the code or data segment where the address is located. The value of
address-mode can be one of the following:
UC[.segment-num, ]
indicates that the address is in the TNS user code space. The segment-num
parameter defines the particular code segment within the user code space.
The value of segment-num must be in the valid range, which (in octal) is 0
through %37. If you omit segment-num, Debug uses 0.
UL[.segment-num, ]
indicates that the address is in the TNS user library space. The segment-num
parameter defines the particular library code segment within the user library
space. The value of segment-num must be in the valid range, which (in octal)
is 0 through %37. If you omit segment-num, Debug uses 0.
SC[.segment-num, ]
indicates that the address is in the TNS system code space. SC is allowed only
in privileged mode. The segment-num defines the particular code segment
within the system code space. If you omit segment-num, Debug uses 5.
The value of segment-num must be in the range 5 through %37 (octal).
SL[.segment-num, ]
indicates that the address is in the TNS system library space. SL is allowed
only in privileged mode. The segment-num parameter defines the particular
[ 32-bit-address ] | [ TNS-style ] | [ Q-mode ] | [ N-mode
]
[ address-mode ] offset [ indirection-type [ index ] ]
