Operation
Alters the value of a symbol.
Format
print Symbol

Value
]
Symbol : Variable name
Value : Value used to alter (decimal, hexadecimal, or symbol)
When this entry is omitted, the current symbol value is displayed.
Conditions: 0
≤
Value
≤
valid range of type
Usage example
n
Example 1
(gdb) info local
j = 0
(gdb)
print j
$1 = 0
When you specify only a variable name, the value of that variable is displayed. The
$
N is a number used to
reference this value at a later time. The contents displayed here can be referenced using
print $1
.
n
Example 2
(gdb) print j=5
$2 = 5
(gdb) info local
j = 5
Note that specifying a value changes the variable value to that specified.
GUI
The values of local symbols can be altered in the [Local Variables] window.
1. Choose a symbol whose value you wish to alter from the symbol list in the [Local Variables] window, then
choose [Edit] from the [Variable] menu or double-click the symbol value displayed.
2. The symbol value is placed in edit mode, so enter a new value for the symbol.
For details, see Section 10.4.8, "[Local Variables] Window".
Notes
• If you specify an undefined symbol, an error is assumed.
• Even if the value you have specified exceeds the range of values for the type of variable you wish to alter, no
errors are assumed. Only a finite number of low-order bits equivalent to the size of the variable are effective,
with excessive bits being ignored. For example, specifying 0x10000 for variable int is processed as 0x0000.
