FRAME-DOWN function

Returns an INTEGER value that represents the number of iterations in a frame.

Syntax

FRAME-DOWN [ ( frame ) ]

frame

The name of the frame whose number down you are trying to determine. If you do not supply a frame name, the FRAME-DOWN function uses the default frame for the block it is in. If the FRAME-DOWN function is in a DO block, the function uses the default frame scoped to the block containing the DO block.

Example

This procedure displays Customers in a frame. When the frame is full, the procedure prompts "Do you want to see the next page?" The procedure recognizes that the frame is full when the value of FRAME-LINE (current logical line number) equals the value of FRAME-DOWN (number of iterations in the frame).

r-frdown.p

DEFINE VARIABLE ans AS LOGICAL NO-UNDO.

REPEAT:
  FIND NEXT Customer NO-LOCK.
  DISPLAY Customer.CustNum Customer.Name.
  IF FRAME-LINE = FRAME-DOWN THEN DO:    
    MESSAGE "Do you want to see the next page ?" UPDATE ans.
    IF NOT ans THEN LEAVE.
  END.
END.

Note

The FRAME-DOWN function returns a value of 0 if used with a single frame or if the frame is not in view when the function is evaluated.
