With z/OS V1R9, SDSF adds the following new function:

• Support for the REXX programming language. This merges the power of SDSF with the simplicity of REXX. Access SDSF data and function with REXX execs. SDSF's REXX support offers a richer alternative to using SDSF in batch mode.
• New columns on the CK panel to support enhancements to IBM Health Checker for z/OS.

With z/OS V1R8, SDSF adds the following new function:

• Enhanced function for job data sets that includes a new action character to hold a data set, newly modifiable columns, and the ability to enter action characters and modify columns under more circumstances.
• Addition of the JES2 job ID to the Processes panel to complement the job name.
• Support for the zAAP and zIIP that includes new columns on the DA and ENC (Enclaves) panels.

With z/OS V1R7, SDSF adds the following new function:

• A new Health Checker (CK) panel that shows information from IBM Health Checker for z/OS and Sysplex, which tests for key z/OS and sysplex values at specified intervals.
• A new Resource Monitor (RM) panel that shows information about JES2 resources, such as JOEs, JQEs and BERTs. From the panel, users can identify resource shortages and view the history for resources.
• New action characters on the MAS panel to display information about the JES2 monitor in the Log, and to stop the monitor.
• New function to allow for a default browse action character (S, SB or SE) on the job, output and CK panels. The default browse action character is invoked when a user selects a row, that is, places the cursor in the NP column and then presses Enter. Users can set the default browse action character with a new SDSF command, SET BROWSE.
• A new option for placement of the cursor on tabular panels that scrolls the last row you worked with to the top of the panel and places the cusor on the command line. This is useful when you define a default browse action character with SET BROWSE.
• An overtypeable USERDATA column to the OD and JDS panels. Up to 16 values can be specified.
• New action characters on the PS panel to provide additional control of z/OS UNIX System Services processes.
• The O action on the H panel is enhanced to allow users to request an outdisp of KEEP. Previously, O always resulted in an outdisp of WRITE. To request KEEP, users type OK.
• Addition of new columns on the DA panel to show zSeries Application Assist Processer (zAAP) usage. These columns were introduced in an SPE (APAR PQ93310) that has been rolled into z/OS V1R7 SDSF.

Support for the JESDATA and NSPBUF parameters in ISFPARMS is removed. These parameters no longer apply in the supported environments. If present, they are ignored.

This release also includes several changes in response to z/OS Consoles changes:

• Support for migration IDs is removed. Users can no longer request a migration ID with the SET CONSOLE command.
• The master console is no longer used to issue system commands. The M prefix can no longer be used with the / command to request a master console.
• New parameters in ISFPARMS provide control over whether an EMCS console is required to issue system commands, and to control the authority used with the EMCS console
