The following controls allow you to set properties for a breakpoint on a memory location:
Address
This box contains the memory address where the breakpoint is set, in decimal or hexadecimal. By default, hexadecimal numbers must be preceded by 0x, for example, 0x1002A. The address must be an integer constant. You do not need to use the 0x prefix for hexadecimal numbers, however, if you have chosen the Hexadecimal Display option in the Options dialog box found on the Tools menu.
Language
This box should show the programming language for that address. If it is not correct, choose the correct language from the drop-down list.
