Few users will use all the features of IOF. Applications programmers may review the jobs they submit, while production control personnel may review a variety of production jobs. Operators may manage output queues and devices such as printers and teleprocessing lines. Systems programmers may review systems tasks, initiators, and offload devices and may write clists or REXX execs to automatically perform any of the above functions.

IOF provides full-screen terminal support in the ISPF, TSO, and CICS environments. Most functions are accomplished by overtyping fields or entering simple commands that are documented on the panel.

In the TSO environment, IOF also runs on line-mode terminals and in TSO batch. It has a full clist and REXX interface to provide programmable access to all the functions that are available to a user at a terminal.

IOF has extensive facilities to review and manage jobs and sysout data sets. While most users can review only the jobs they submitted, authorized users can manage larger queues of jobs. IOF has panels to display job status and return code summaries. IOF allows you to cancel or release jobs and to modify many job characteristics. A user can browse, release, modify and cancel individual sysout data sets using full-screen facilities.

IOF provides full-screen support for all JES2 controlled devices and initiators. This includes printers, punches, readers, teleprocessing lines, remotes, network devices, and offloaders. All device attributes can be displayed on a full-screen panel and can be modified by authorized users by simply overtyping.

When running IOF in the TSO environment, the System Log Access and Management and the sysplex operlog. (IOF/SLAM) facility provides fast and effective access to the system log. IOF/SLAM builds a comprehensive index to the log data which allows immediate access to any minute in the log. Additionally, important error and exception conditions in the log are indexed to make them easy to detect and review.

The IOF System Monitor displays all active address spaces in the system and can be sorted by any display field. Specific types of address spaces can also be requested from a full- screen monitor interface panel. Authorized users can use the monitor as an effective tool for detecting and correcting system errors and bottlenecks.

IOF extended MCS console support gives authorized users the ability to enter MVS and JES2 commands and to see command responses on a scrollable panel.

In the TSO environment, IOF provides a fully programmable interface to the JES2 subsystem. All IOF job, device, initiator, monitor and system log facilities are fully accessible through clists or REXX execs running both interactively and in batch TSO. Several significant clists and execs are distributed with the product and can be used productively by supplying clist parameters.

IOF provides many unique features to aid users running in a multiple CPU environment. The Operlog function displays the combined sysplex system log. The MAS display shows the status of each CPU in the complex. The IOF server function allows users to start an IOF session on any CPU in the sysplex.
