SCR_LINE( )
The SCR_LINE( ) function returns a positive integer, corresponding to the
number of the current screen record in its screen array during a DISPLAY ARRAY or
INPUT ARRAY statement.
The current screen record is the line of a screen array that contains the
screen cursor at the beginning of a BEFORE ROW or AFTER ROW clause.
The first record of the program array and of the screen array are both
numbered 1. The built-in 4GL functions SCR_LINE( ) and ARR_CURR( ) can return
different values if the program array is larger than the screen array.
