Retrieve values that can be used as variables

This addresses how to retrieve values such as system values and job attributes to use as variables in a procedure. Note that not every possible retrieve value is included.

• Retrieve system values
  A system value contains control information for the operation of certain parts of the system.
• Retrieve configuration source
  Using the Retrieve Configuration Source (RTVCFGSRC) command, you can generate CL command source for creating existing configuration objects and place the source in a source file member.
• Retrieve configuration status
  Using the Retrieve Configuration Status (RTVCFGSTS) command, you can give applications the capability to retrieve configuration status from three configuration objects: line, controller, and device.
• Retrieve network attributes
  Using the Retrieve Network Attributes (RTVNETA) command, you can retrieve the network attributes of the system.
• Retrieve job attributes
  You can retrieve the job attributes and place their values in a CL variable to control your applications.
• Retrieve user profile attributes
  Using the Retrieve User Profile Attributes (RTVUSRPRF) command, you can retrieve the attributes of a user profile (except for the password) and place their values in CL variables to control your applications.
• Retrieve member description information
  Using the Retrieve Member Description (RTVMBRD) command, you can retrieve information about a member of a database file for use in your applications.
