Field-Characteristic Clauses
Using a Control Structure
A screen field specifying a CONTROLLED clause associates itself with a Working-
Storage or Linkage Section data item (data-name-1) that supports run-time control
and definition of the screen field’s display attributes. The associated control structure
becomes operative only when the DISPLAY BASE DYNAMIC, DISPLAY OVERLAY
DYNAMIC, and TURN DYNAMIC OPERATIONS clauses are invoked. Table 5-4
shows the effect of the CONTROLLED clause on the formation of screen field attributes
during these operations.
