The FROM Clause
The FROM clause identifies the source of data for display.
General Format

Syntax Rules
- The FROM clause, when used with the TO clause, is equivalent to the USING
clause, both specifying the same identifier. It must not be used with the
USING clause.
- The identifier in the FROM clause can be qualified. If no OCCURS clause applies
to the screen item, this identifier can be subscripted or indexed. It must
be defined in the File, Working-Storage,
Local-Storage,
or Linkage Section of the program.
General Rules
- Executing a DISPLAY statement on a screen item whose description includes
a FROM clause moves data from the associated data item to the screen item,
and then displays the screen item on the screen.
