You can test FOCUS on the production disk as follows:

1. Define the virtual machine size as in the first Step in Test the Generated Version of FOCUS.
2. IPL CMS.
3. Access two cylinders of temporary storage as A, in READ/WRITE mode.
4. Access the production disk as B/B, which makes it read only.
5. Release all other disks except the CMS system disks.
6. Enter FOCUS.

   Enter FOCUS by executing the CMS EXEC named FOCUS:

   EXEC FOCUS

   FOCUS is always entered using this CMS EXEC, which is created by the GENFS EXEC, which inserts your FOCUS segment name. When FOCUS is entered it displays the release banner. You should see a single caret (>).

7. Test the terminal I/O.

   Press Enter without typing anything else, not even a blank. The response you should receive is simply the word FOCUS.

8. Execute the FOCUS test procedure.

   Issue the following command:

   EXEC CARTEST

   This test FOCEXEC runs through the major test areas and prints reassuring messages if all is well. Press Enter (in full-screen mode) and CLEAR to page through the test. The end of this short test is signaled by the message:

   AT END OF TEST MAJOR AREAS OK

   You can return to the CMS command level by issuing the FOCUS command FIN when you receive the above message.
