z/OS UNIX file system support in ISPF
The Interactive System Productivity Facility (ISPF) product helps with program development and uses the characteristics of IBM display terminals to increase users productivity in an interactive environment.
This chapter describes the new z/OS UNIX file system support in ISPF that is introduced with IBM z/OS V2R2 and includes the following topics:
3.1 New functions for the ISPF option 3.17
In z/OS V2R2, the following file system-related functions were added to ISPF option 3.17:
•The z/OS UNIX ISPF Shell (ISHELL) file system functions were added.
•Enhanced displays for mounted file systems:
– Lists can be shown ordered by file system name or mount point name.
– Lists can be expanded and collapsed to improve usability.
The enhancements have the following advantages:
•File system functions are consolidated in a single location. In older versions, the following functions were available with UNIX file systems:
– Mount Table functions in the z/OS UNIX ISPF Shell (ISHELL)
– z/OS UNIX Directory List Utility (udlist) of ISPF option 3.17
•The usability for displaying mounted file systems was improved.
•There are practical usability issues when many file systems must be displayed and managed in the ISHELL mount table.

Note: Consider the following points:
•The ISHELL is still available for use. The mount table function is still used often.
•If udlist was used in parallel with the ISHELL mount table, see “Utility RXISHMT” on page 42 for more information about an ISHELL mount table only function that is used with filter functions.
