Modifying memory through the hexadecimal data area

You can type over the hexadecimal data area with hexadecimal characters (0-9, A-F, a-f). z/OS® Debugger updates the memory with the value you typed in. If you modify the program instruction area of memory, z/OS Debugger does not do any STEP commands or stop at any AT breakpoints near the area where you modified memory. In addition, if you try to run the program, the results are unpredictable.

The character data column is the character representation of the data and is only for viewing purposes.
