Additional Information for TDF Presentation
When a trap is initialized for a program via TDFHOOK or dynamically via a Dynamic Program Intercept such as an attach or SRB, the program enters a diagnostic pause and is placed in the TDF active dispatchable unit list. The ISPF User Interface provides a list function to access this list. From this list, you can select (S) a dispatchable unit for debugging, end all debugging (E) or leave all debugging options and release the application until it encounters another trap (G).
