Disassemble Output
Both the disassembler and memory dump panes of the debugger allow a selected area of memory to be disassembled.
The options allow output to be directed to either a New Assembler Tab, which will create a new file in the disassembler, an Existing Assembler Tab which can be selected from the list, or a File.
The output will normally replace the existing contents of the selected file, unless you click the Append Output check box.
