Displaying a Single Instance on One Screen: The SINGLE and MULTIPLE Commands

To display a single instance on the screen, enter:

SIngle

This places you in SINGLE mode. SINGLE mode enables you to view a single segment instance on one screen. Only the current instance appears, but all its fields appear on one screen (unless it has many fields). You may enter all FSCAN commands on the command line at the bottom of the screen, but there is no prefix area. The key field values appear highlighted.

All FSCAN commands (but not prefix area commands) operate in SINGLE mode, except that only one instance is displayed. In particular, note the following:

If you enter the FORWARD command in SINGLE mode, FSCAN displays the next instance in the segment. If you enter the BACKWARD command, FSCAN displays the previous instance.
If you enter the CHILD command, only one child instance appears at one time. If you enter the PARENT command, only the parent instance of the current instance appears on the screen.

You can update and delete an instance in SINGLE mode, but you cannot add another instance.

You remain in SINGLE mode until you enter the command:

Multiple

MULTIPLE returns you to normal mode, which displays multiple instances at one time.

Example: Using SINGLE Mode

For example, this is how Diane Jones' instance looks in SINGLE mode. Note that there is no input area, and that the arrow at the bottom of the screen points to the command line where you can enter commands:

  FSCAN FILE EMPLOYEEFOCUS A1                CHANGES : 0
