  - 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).
    - DELETE – Delete object from database or plan
      Use the DELETE request to delete a record or record segment.
    - EXECUTE – Commit updates to the Current Plan
      Use the EXECUTE request to update the current plan after one or more modify, insert, or delete current plan requests are completed.
    - INIT – Initialize communication with IBM Z Workload Scheduler
      Use the INIT request to identify the required IBM Z Workload Scheduler subsystem and initialize the communication session between the subsystem and Workload Automation Programming Language.
    - INSERT – Add objects into the plan
      In Workload Automation Programming Language, use the INSERT request to add occurrences to the Current Plan and Long-Term Plan. The PIF facility to update the database is handled by Batch Loader within Workload Automation Programming Language.
      - INSERT CPCOND – Current Plan Condition
      - INSERT CPLAT – Operation User-defined Late Information
      - INSERT CPOC – Current Plan Occurrence
      - INSERT CPOCPRE – Current Plan Occurrence Predecessor
      - INSERT CPOCSUC – Current Plan Occurrence Successor
      - INSERT CPOP – Current Plan Operation
      - INSERT CPPRE – Current Plan Predecessor
      - INSERT CPSAI – Current Plan System Automation Info
      - INSERT CPSIMP – Current Plan Conditional Predecessor
      - INSERT CPSR – Current Plan Operation Special Resource
      - INSERT CPSUC – Current Plan Successor
      - INSERT CPUSRF – User Field
      - INSERT IVL – Current Plan Workstation Interval
        If an interval contains information originating from the workstation description, indicator CPIVLDP in segment CPIVL is set to Y otherwise it is set to N. If an interval is changed through the dialog or program interface, the indicator CPIVLMOD is set to Y, or otherwise it is set to N. INSERT IVL can insert an interval spanning existing intervals with CPIVLMOD=N.
      - INSERT JCLPREP – JCL Preparation
      - INSERT LTOC – Long Term Plan Occurrence
      - INSERT LTPRE – Long Term Plan Predecessor
      - INSERT VIVL – CP Virtual Workstation Interval
        An interval can have information originating from the workstation description, indicator CPVIVLDP in segment CPVIVL is set to Y, or otherwise to N. If an interval is changed via the dialog or the program interface then the indicator CPVIVLMOD is Y, or otherwise N. INSERT VIVL can insert an interval spanning existing intervals with CPVIVLMOD=N.
    - LIST – Find objects in the Database and Plans
      Use the LIST request to retrieve a list of records of a selected type.
    - MODIFY – Modify objects in the plans
      Use the MODIFY request to modify one or more fields in an LTP or CP record.
    - REPLACE
      The REPLACE request is performed by Workload Automation Programming Language internally using the Batch Loader functionality to build records before writing them to the database.
    - RESET – Resets pending changes to the plan
      Use the RESET request to delete the current Modify Current Plan (MCP) block.
    - SELECT – Retrieve a record or common segment
      Use the SELECT request to retrieve a record by specifying field names and values that identify the record you want to retrieve.
    - SETSTAT – Sets a Condition status
      The SETSTAT request changes the condition status from undecided to true or false, if the original status was undecided because of missing step-end information.
    - TERM – Terminate IBM Z Workload Scheduler session
      Use the TERM request to terminate the programming interface session and perform the cleanup processing.
  - 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.
  - Resource reference
  - OPTIONS keywords
    Use the following keywords with the OPTIONS statement.
  - Workload Automation Programming Language variables
    In addition to the IBM Z Workload Scheduler variables and user variables, Workload Automation Programming Language has access to some additional information relating to the job running Workload Automation Programming Language and when scheduled the operation and occurrence within which it is running.
  - WAPLEXEC programs
    The Workload Automation Programming Language for z/OS is a REXX based tool provided to give you easy access to the features of the IBM Z Workload Scheduler Program Interface (PIF). Workload Automation Programming Language can be extended by WAPLEXEC programs, which are REXX programs using Workload Automation Programming Language functions to tackle specific tasks or functions.

INSERT CPOC – Current Plan Occurrence

Table 1. INSERT CPOC – Current Plan Occurrence
Argument Name	Description
ADID	Application description ID as stored in the database
ALIAS	Application description ID to use on the Current Plan
DEADLINE	Deadline date and time YYMMDDHHMM
DESC	Descriptive text
ERRCODE	Error code
GROUP	Authority group
GROUPDEF	Group definition ID
IA	Input arrival date and time YYMMDDHHMM
JCLVTAB	JCL variable table
ODESC	Descriptive text of owner
OWNER	Owner ID
PRIORITY	Priority

Note:

A DEADLINE argument is accepted also when no IA argument is specified. If the IA selected by IBM Z Workload Scheduler is later than the DEADLINE argument value, the argument value is ignored. The default, IA plus 8 hours, is used.
If you specify 24.00 as the IA time, it is converted to 00.00 of the following day. Valid input arrival times are from 00.00 to 23.59.
If you specify 00.00 as deadline, it is converted to 24.00 of the previous day. Valid deadline times are from 00.01 to 24.00.
If you use ALIAS, unique occurrences could be created in the plan; but if another application with the same name exists, this is never run and the JCL for these occurrences remains in the JS file indefinitely. Consider using the IBM Z Workload Scheduler sample EQQPIFJX to maintain the JCL repository.
