You can obtain status for a data set using the Extended Status subsystem interface (SSI 80) code. To do this, you supply as STATCTKN the address of the CTOKEN for the data set you are interested in and set the selection flag STATSCTK. When you use the STATSCTK selection flag, you cannot use the STATSJBI selection flag, and vice versa.

Refer to SSI 80 in z/OS MVS Using the Subsystem Interface for a detailed description of the Extended Status call.
