ISPF: How do I display the active libdefs?

With ISPF you can define additional files for the ISPF libraries, such as ISPPLIB, ISPMLIB using the LIBDEF command.

You can display the current LIBDEFS using the ISPLIBD command. I remember this name because it is ISP for ISPf …. LIBraray Display – so ISPLIBD.

If you want to see what data sets are allocated use the TSO ISRDDN command.
