Operation
Opening/closing the window
The [Local Variables] window does not open automatically at debugger startup (unless the gdbtk.ini file is
changed).
To open the window, choose [Local Variables] from the [View] menu in the [Source] window or click the [Local
Variables] button.
[Local Variables] button
Click the [Close] button to close the window. The window can also be minimized.
Only one instance of the [Local Variables] window can be open at a time. Any attempt to open the [Local
Variables] window while already open reactivates the [Local Variables] window and moves it to the front of the
screen.
Changing display format
The format in which to display variable values can be selected from the following:
Hex: Hexadecimal
Decimal: Signed decimal
Binary: Binary
Octal: Octal
Natural: Common representation for the data type (e.g. decimal for int type values, hexadecimal for
pointers) (default)
Select a variable whose display format you wish to change by clicking on its line in the window.
Next, choose the desired display format from the [Format] submenu of the [Variable] menu.
Otherwise, you can choose a display format from the popup menu shown below that appears by right-clicking.
rewriting variable values
Variable values can be changed directly in the window.
Select a variable whose content you wish to change by clicking it in the window.
Next, choose [Edit] from the [Variable] menu or the popup menu that appears by right-clicking. The variable
value will be highlighted with a blue background while a text cursor appears behind the value, indicating that
the variable is in edit mode. You also can enter edit mode by double-clicking a variable value.
Enter a new value in decimal or hexadecimal to replace the existing value or change the necessary digits of the
existing value. You can use the arrow, backspace, and delete keys.
Entering a value exceeding the data size of the variable only applies the low-order effective bits and ignores the
bits outside the valid range.
limitations
• The local variable values displayed in the [Local Variables] window are not updated even when using a
command to correct the contents of these values. Variable values are only updated when changed during
program execution.
• The value of the variable, which is allocated to a register, may not be displayed properly due to the
optimization by the C compiler.
