  - Overview
    The Workload Automation Programming Language is a programming language that provides you with easy access to the features of the HCL Workload Automation for Z 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 HCL Workload Automation for Z 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 HCL Workload Automation for Z; 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 HCL Workload Automation for Z 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 HCL Workload Automation for Z 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 HCL Workload Automation for Z 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.
  - Messages and Return Codes
    Messages and return codes provide information for problems occurred.
