Modifying Existing Resource Classes

The user may want to modify an existing resource class to change its attributes. For example, the user can add default protection by assigning the DEFPROT attribute to the appropriate TSS command function.

Note: For predefined resource classes, only EXIT, DEFPROT, MASK, and MERGE attributes can be used.
