Examining Memory and Disassembling Code

assign register = expression

Assigns the value of expression to register. You must precede

the name of the register with a dollar sign ($).

For example:

(dbx) assign $f0 = 3.14159

3.1415899999999999

(dbx) assign $t3 = 0x5a

0x5a

By default, the assign register command changes the register value in the

current activation level, which is a typical operation. To force the hardware

$framereg command.

Examining Memory and Disassembling Code

The forward slash (/) and question mark (?) commands allow you to

examine the contents of memory. Depending on the format you specify, you

can display the values as numbers, characters, or disassembled machine

code. Note that all common forms of address are supported. Some unusual

expressions may not be accepted unless enclosed in parentheses, as in

(address)/count format.

The commands for examining memory have the following syntax:

address / count format

Prints the contents of the speciﬁed address, or disassembles

the code for the instruction at the speciﬁed address. Repeat

for a total of count addresses in increasing address—in other

words, an “examine forward” command. The format codes

are listed in Table 7-2.

address ? count format

Prints the contents of the speciﬁed address or, disassembles

the code for the instruction at the speciﬁed address. Repeat

for a total of count addresses in decreasing address—in

other words, an “examine backward” command. The

format codes are listed in Table 7-2.
