How do you clear a flat file in JCL?
If you have an input file and after successfully reading the data your requirement is to “empty” the file you can do this within your COBOL program that reads the file. Open the file as input and read until end-of-file. When the AT END is reached, close the file. NOW – open the file as output and close the file.
How can I tell if a VSAM is empty?
By using IDCAMS repro also empty check can be done. If the return code is 4 (RC=4), then the file is empty. 3. If the return code is Zero (RC=0) then file is not empty otherwise it is empty and return code would be 12 if it is empty .
