What’s new in z/OS V2R5 ISPF?

In a matter of months, the world has been transformed due in part to the COVID-19 crisis. Enterprises are putting new emphasis on resiliency, recovery, and cybersecurity. With z/OS V2R5 coming soon in this September, the classic hits keep coming from IBM, which will give you more performance, agile development, application modernization, and more importantly, the cloud you want with the privacy and security you need.

Interactive System Productivity Facility (ISPF), a full-screen and menu-driven interface which lets you access z/OS tools and utilities, is familiar to everyone who interacts with z/OS. With z/OS V2R5, ISPF provides incremental improvements to ease of use.


Message enhancements for PDSE v2 member generations

ISPF has provided very basic support for PDSE V2 member generations since DFSMS provided the capability in z/OS V2R1. In V2R5, the ISPF support is enhanced to provide improved messages when you need to edit, browse, or view members that are enabled for PDSE v2 member generations. 

With improved messages, you can clearly tell which generation you are editing, how many generations there are, and the results of saving an edited generation.

Here is an example of the improved message ISRE494 on the ISPF edit panel.

This is an edit session of the current generation for member ABC. When you issue "save NEWGEN" from the command line to save the current generation, message ISRE494 is issued to indicate how many generations are in use. 

  • Short version: Indicates that member "ABC"is saved.
  • Long version: You can also hit PF1 to display the long version of message ISRE494 for more details. It specifies that "1" non-current generation is saved. "20" is the maximum.
  • Use the member information panel to determine what generations are currently allocated and in use.
  • Hit PF1 to display the long message version of various member generation messages. The long version contains more details and can be very helpful.

Support for SUBSYS parameter on the ISPF SUBMIT command

With this optional SUBSYS parameter, you can submit jobs to an alternate JES other than the primary subsystem.
Useful when: Directing jobs to the JES2 emergency subsystem
Within ISPF, you can issue the SUBMIT command from:
  • Edit Primary command line
  • Browse Primary command line
  • Within Edit Macros
Here is an example of issuing the SUBMIT command from the ISPF edit session.
