I am developing a project that requires some fields to dynamically change their attributes from protected to unprotected and vice-versa as per given user's choice on clicking a button. I just want to confirm that using DFHBMUNP and DFHBMPRO will be sufficient alonwith copybuk DFHBMSCA?? Are there any changes that should be made in MAP programming ?? I am new to COBOL so kindly explain whole process
