COBOL on System/Z doesnt even know how to do file I/O, you set up the I/O in the JCL job that loads the COBOL application.

- p_l 6y agoThat's just the default way of handling I/O on MVS descendants, but it's not the only one - pretty sure you can allocate and configure new "file open records", but it would make your program less portable ;) and there's rarely a need.
- rbanffy 6y agoThe very concept of files is alien. You have datasets that look like card stacks or tapes. You don’t expect files and directories on machines that predate disks.
