Standard streams

Under z/OS Language Environment there is no longer an automatic association of ddnames SYSTERM, SYSERR, SYSPRINT with stderr. Command line redirection of the type 1>&2 is necessary in batch to cause stderr and stdout to share a device.

In C/370™ Version 1 and Version 2, you could override the destination of error messages by redirecting stderr. Language Environment determines the destination of all messages from the new MSGFILE runtime option. For more information about the MSGFILE option, see z/OS Language Environment Programming Guide.
