I am having a Sequential File,Thru COBOL Pgm. I am Processing & writining Records To the File. If Job Abends then Records Should get written to the File & when I restart the Job from Abended Step, Records which are not processed
Should get Added to The File. For This I am Using Disp = (MOD,CATLG,CATLG). Please Confirm from COBOL side do I Need to Open the File in Extend Mode Or Output Mode will also work. My Understanding is EXTEND Mode. Please Confirm If I am wrong.
