The FROM Clause

The FROM clause identifies the source of data for display.

General Format


Syntax Rules

  1. 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.
  2. 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,

    MF Local-Storage,

    or Linkage Section of the program.

General Rules

  1. 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.
