Problem with display - Header area is not displayed

Display file issue when control returns
there are two ways you can handle this problem one is by

Method one:
When you refresh your program decides it did not find any
data, therefore does not turn on SFLDSP, which means
the 'subfile part' of the screen does not change. So try and turn the SFLDSP on when the
control comes back to pgma

or Method Two:
Code an ERASE(sflname) in the Control record. Condition it so it comes on when you do a SFLDSPCTL without a SFLDSP.
