The Interface now resides on your system. Before you invoke the Interface, you must do two things:

• Create a program (a CLIST or REXX EXEC for TSO, a FOCEXEC for MSO, or JCL for a batch environment) that invokes FOCUS, with the Interface, from each environment you installed. Environments, includes sample CLISTs and JCL.
• Invoke FOCUS and run a simple query to test the Interface installation.

  The following sample request uses the DI21PART Master File that is supplied with the Interface. Before submitting this request, make sure you created a FOCPSB for the PSB you use with the DI21PART database. FOCPSBs are discussed in Creating FOCUS Descriptions. Sample File Descriptions includes examples of a PSB and a FOCPSB for DI21PART:

  TABLE FILE DI21PART
  PRINT PARTKEY
  IF RECORDLIMIT EQ 10
  END
