If the FOCUS data source has a file ID other than the default, issue the USE command to identify the data source, with its file specifications, and associate it with a specific Master File.
fileid AS mastername END
where:
Is any valid file specification for the specific operating system.
Is name of the Master File name that will be associated with the file ID.
To read the data source with the name EMP026 described by the Master File EMPLOYEE, enter this USE command:
|
For CMS: |
USE EMP026 FOCUS A AS EMPLOYEE END
|
|
For z/OS: |
USE EMP026 AS EMPLOYEE END |
After entering the USE command, you can read the EMP026 data source by entering the command TABLE FILE EMPLOYEE.
|
For CMS: |
To read the data source with the name EMP026 and a file type of DATA on the A-disk, described by the Master File EMPLOYEE, enter this USE command: USE EMP026 DATA A AS EMPLOYEE END |
After entering the USE command, you can read the EMP026 data source by entering the command TABLE FILE EMPLOYEE.
|
For CMS: |
To read the data source with the name EMP026 located on the F disk, described by the Master File EMPLOYEE, enter this USE command: USE EMP026 FOCUS F AS EMPLOYEE END |
The first data source in the USE directory defines the default file type and file mode for the rest of the session or until you clear the USE directory. For example, if you later issue the command TABLE FILE PRODUCT, FOCUS searches for the data source PRODUCT FOCUS F even if you did not specify the data source in the USE command. If you want to read both EMPLOYEE FOCUS F and PRODUCT FOCUS A, issue:
USE EMP026 FOCUS F AS EMPLOYEE PRODUCT FOCUS A END
Since PRODUCT FOCUS A is the second entry in the USE directory, the default file mode remains F.
