Hi I am new to Cobol/400 and writing one program where the user will enter the Customer No. IF customer number is not present in DB then error message should be displayed " Customer invalid" for this i have defined the Indicator 21 in the DSPF. On providing the wrong customer number error message is not displayed. On providing the correct customer number details are displayed. Please help me out how to display the error message. Below is the DSPF DDS and Cobol program.
