FORM PAGING USING CODE.

DATA: I TYPE I.

J TYPE I.

CASE CODE.

WHEN 'P--'. FLIGHTS-TOP_LINE = 1.

WHEN 'P-'. FLIGHTS-TOP_LINE = FLIGHTS-TOP_LINE - LINE_COUNT.

IF FLIGHTS-TOP_LINE LE 0.

FLIGHTS-TOP_LINE = 1. ENDIF.

WHEN 'P+'. I = FLIGHTS-TOP_LINE + LINE_COUNT.

J = FLIGHTS-LINES - LINE_COUNT + 1.

IF J LE 0.

J = 1. ENDIF.

IF I LE J.

FLIGHTS-TOP_LINE = I.

ELSE. FLIGHTS-TOP_LINE = J.

P+, P, P--, P-. I would think would be the user commands associated with scrolling or using the page up and page down icons (ok_codes that you define in the status bar,

P+ would be scroll down one page

P++ would be scroll to the end

P- would be scroll up one page

P-- would be go back to the beginning

Form the looks of the code, I suspect flight_lines would be the total number of lines in your internal table so that the rpogramcan decide from which line it should show the data if in a table control.

Hope this helps.
