Examples of the On Modify Breakpoint

To set a stop On Modify breakpoint to stop whenever the address that contains y is modified, you would set the following in the Details pane:

• Event On Modify &y
• Action Stop
• Option None

You can set an On Modify breakpoint to stop when the contents of a string changes. For example, your program has a variable defined as:

char *sp = "hello world\n"	

To find where a change occurs in the value of sp by setting the following in the Details pane:

• Event On Modify sp, 12
• Action Stop
• Option None

The sp does not require an ampersand (&) because you want to watch the string.

Note - If the variable you want to track is visible in the Debugging or editor window, you can select the expression, then choose Data Stop on Modify Selected. Use the action Stop with On Modify to stop when a variable reaches a certain number.
