Input and Output

IEHLIST uses the following input:

One or more source data sets that contain the data to be listed. The input data set can be:
- A VTOC
- A partitioned data set or PDSE
A control data set, that contains utility control statements that are used to control the functions of IEHLIST.

IEHLIST produces as output a message data set that contains the result of the IEHLIST operations. The message data set includes the listed data and any error messages.

If IEHLIST is invoked from an application program, you can dynamically allocate the devices and data sets by issuing SVC 99 before calling IEHLIST.
