Debugging in browse mode

When you debug in some production environments, it might be necessary to restrict your ability to change storage contents and execution flow. Debugging in browse mode enables you to debug your programs while restricting your ability to change storage contents and execution flow. z/OS® Debugger uses the RACF® authority of the current user, an EQAOPTS command, or both to determine whether to operate in browse mode.

When you debug in browse mode, you can not do the following actions:

Modify the contents of memory or registers
Alter the sequence of program execution

You can use the QUERY BROWSE MODE command to determine if browse mode is active.

For information on how to install and control browse mode, see IBM® z/OS Debugger Customization Guide.
