Configuring and Writing REXX › Invoking REXX Programs

Invoking REXX Programs

You can invoke a REXX program in the following ways:

• From the CA Automation Point command area or from the workstation's operating system prompt

  From the command prompt, specify the REXX program and any optional arguments as follows:

  asorexx rexxprog arguments
  

  Note: If necessary, you can explicitly specify the directory where the REXX program resides. For information about CA Automation Point file directory structure, see the chapter "Configuring CA Automation Point."

  With a REXX program, you can automate a long, command-intensive operator task, such as logically partitioning a mainframe processor and IPLing the partitions. Instead of manually issuing a series of CA Automation Point commands, system commands, or other types of commands, you can save time by manually invoking a REXX program to issue all of the necessary commands automatically.

• From a CA Automation Point rule

  When a task is too complex to be automated exclusively with CA Automation Point rules, you can use rule-initiated REXX programs to perform automation. You may want to invoke REXX programs in this way when:

  • Making the proper response to a message is too complicated
  • Rules cannot provide all of the information needed
  • The REXX program must execute at a particular time or after a specified time interval
• From another REXX program

  The CA Automation Point REXX command processor allows you to invoke one or more REXX programs from within a single REXX program. All REXX programs queued by the original program can run concurrently while the original program continues to execute.

• By selecting REXX program(s) for CA Automation Point to run at startup

  You can select these programs in Configuration Manager from the REXX Settings dialog.
