You can use IDF to debug an application program that needs an ISPF environment present, if SVC 97 is used for breakpoints.

Notes:

The IDF session cannot be invoked from within ISPF. It must be invoked from the TSO/E ready prompt.
If the library containing the program to be debugged does not reside in the STEPLIB or ISPLLIB allocations, use TSOLIB ACTIVATE to include the load library, or allocate the library and invoke IDF using the LIBE option to specify the allocated DDNAME.

The following examples describe a number of ISPF application debug scenarios.

To debug an ISPF dialog program which resides in a data set in the STEPLIB allocation:
From the TSO/E READY prompt:
```
    TSOEXEC ASMIDF XYZZY  (COMMAND/ISPSTART PGM(XYZZY)
```
Once in IDF,
```
   BREAK (XYZZY)
```
then
```
   RUN
```
To debug an ISPF dialog program which resides in a data set in the ISPLLIB allocation:
From the TSO/E READY prompt:
```
    TSOEXEC ASMIDF XYZZY  (LIBE ISPLLIB COMMAND/ISPSTART PGM(XYZZY)
```
Once in IDF,
```
   BREAK (XYZZY)
```
then
```
   RUN
```
