Just copy an empty file (i.e. DD DUMMY) into it.

Also, this is another good option. I like this one because you don't need to be concerned with the RECFM and LRECL of the dataset:

If this has to be done with COBOL, open the file in OUTPUT mode and don't write anything in it -- and you are done.

Your req isn't clear. If you just want to clear the file of its data, Anuj's reply is the way to go - open/close the file as O/P.

If you want to use the file for your own data, open as O/P, WRITE what you want, then close it. The last rec ptr will be re-set to the last rec you wrote.

Just remember the file attributes have to be the same as the orig file.

I'm confused. If it's a gdg then why would you want to empty it? When you write a new gdg then the 0 one will have your new data and the -1 will have the old contents.
