  - About this publication
  - Overview
    The Workload Automation Programming Language is a programming language that provides you with easy access to the features of the IBM Z Workload Scheduler Program Interface (PIF).
  - Running Workload Automation Programming Language
    You can run Workload Automation Programming Language as a batch job by using the compiled REXX exec, as a load module, online within a TSO session, as a started task workstation, or as a console command. A user program must run as an authorized program.
  - Core programming commands
    The following sections describe the Workload Automation Programming Language commands that control the behavior and logic of the program. Use the commands to set options, return codes, determine an output, modify the flow, change variables, or make decisions.
  - Workload Automation Programming Language functions
    Some commands in Workload Automation Programming Language operate in REXX mode. These commands are CONSOLE, DISPLAY, DO, IF, LOG, SETVAR when the equal sign (=) is used, and WRITE.
  - Data Access commands based on PIF
    The Data Access commands supported by Workload Automation Programming Language are low level commands based on the IBM Z Workload Scheduler programming interface (PIF).
  - Current Plan Operation commands
    Use the Current Plan Operation commands to perform specific functions against operations in the current plan, using a common set of keywords to identify the operation you want.
  - Current Plan Occurrence commands
    Use the Current Plan Occurrence commands to perform specific functions against all operations within a single occurrence in the current plan, using a common set of keywords to identify the occurrence.
  - Function Based commands
    The Function Based commands combine various low level PIF commands. Use the Function Based commands to perform specific scheduling or operational functions.
  - Using TSO commands within Workload Automation Programming Language
    Some TSO commands are specific to IBM Z Workload Scheduler; you can run them natively in TSO, through program EQQEVPGM, and through Workload Automation Programming Language.
  - Batch loader commands
    The batch loader function of Workload Automation Programming Language uses a set of statements to define or modify objects within the IBM Z Workload Scheduler database.
  - Variable substitution
    Workload Automation Programming Language supports variable substitution within its control statements. In this way, the actual values required for each command run are provided (for example, the occurrence name or Input Arrival date).
  - Performance considerations
    With Workload Automation Programming Language you can use different methods to perform the same action. Each method has different implications for ease of use and performance, the balance of which might change depending on the volume of records to which it is being directed.

      States the unit to specify durations.
    - DYNATTR – Set attributes for dynamic log
      The OPTIONS DYNLOG keyword causes a dynamic log file to be created to save a copy of the Workload Automation Programming Language log.
    - DYNLOG – Create a dynamic copy of the Workload Automation Programming Language log
      During parallel testing, if the OPTIONS FAIL(N) or SPOOF keywords are used, you cannot identify the problems with the IBM Z Workload Scheduler part of the processing. This keyword prompts Workload Automation Programming Language to create a copy of the log in a uniquely named data set, so that the logs can be collated and scanned for errors at points in the testing cycle.
    - EXECUTE – Automatic Current Plan EXECUTE
      Automatically performs an EXECUTE before termination.
    - EXPAND – LIST related objects
      Whether to generate LIST statements for any database elements that might be required by a SELECTed database element.

FAIL – Action to take with return codes

In normal use, Workload Automation Programming Language is expected to fail with non-zero return codes in the event of errors being found. However, during parallel testing when migrating from an alternative workload automation product to IBM Z Workload Scheduler, it is normal to send commands to IBM Z Workload Scheduler first, then to the alternative product that is controlling the workload. This enables IBM Z Workload Scheduler to be in the correct state to track events from the alternative product.

The following values are valid for FAIL:

YES: Default. Workload Automation Programming Language flushes commands after the OPTIONS STOPRC return code is issued, and returns the highest return code back to the running job.
NO: Workload Automation Programming Language continues processing commands even if the OPTIONS STOPRC return code has been reached, and in most circumstances ends with return code zero. Severe syntax issues causes the Workload Automation Programming Language step to fail, but these should be eliminating in testing before parallel running. All error messages will be echoed to the SYSLOG to be collected as part of the parallel testing process.
QUIET: Workload Automation Programming Language continues processing commands, even if the OPTIONS STOPRC return code has been reached, and in most circumstances ends with return code zero. Severe syntax issues causes the Workload Automation Programming Language step to fail, but these should be eliminating in testing before parallel running. No error messages will be echoed to the SYSLOG.

Note: OPTIONS FAIL overrides any return codes from commands, including SETMAX, but is overridden if OPTIONS SPOOF is coded.
