The POSTEXIT gets control after TCF test compresses the data set and computes statistics.
The parameter list that is passed to the exit is shown in the following table.
Note: The statistical fields contain binary zeroes when TCF is run in simulation mode.

INPUT |
CL44 |
Data set Name-The name of the data set currently being processed. |
|
|
INPUT |
Halfword |
Volume Count-The total number of volumes to which the data set is cataloged. This is also the number of volumes that is presented below in the Volume List parameter. |
|
|
INPUT |
nCL6 |
Volume List-A list of the volumes to which the data set is cataloged. The number of volumes appearing in this list can be determined by examining the Volume Count parameter above. |
|
|
INPUT |
CL3 |
Data set Organization-This is a literal value indicating the data set organization. The valid values are 'VS' for VSAM data sets and 'PS' for physical sequential data sets. |
