  • using DSPATR(ND) in DSPF second record format hides the First record format in Cobol

    I am writing one cobol program where in the first record format user need to enter the customer number. If the customer number is not found then error message 'Customer Not Found" on line 23 sholud be displayed. If the customer number is found then customer details should be displayed (Second record format) along with the first one. In DSPF file in the first record format I have define one output field and make it non display with indicator N21. Now when the customer is not found then this get displayed with message 'Customer not found' working fine.
    The issue is that when customer is found then only detail record format is displayed. The first one gets hide and on pressing enter key then first one is displayed back.
    Please see the DSPF DDS and cobol program. Please help me out how to display the detail screen along with the first screen.

    When you want to display a second record format while keeping the first one on the display, the second record format cannot overlap the first record format. In your example, the first record format spans from line 1 to line 23 and the second record format spans from line 7 to line 11 which overlaps the first record format, even though there is no data displayed between line 7 and 11 in the first record format. To fix the problem you could remove the ERRORMSG field from the first record format and put it in it's own record format or you could move the ERRORMSG field from line 23 to a line between 1 and 6.
