Differences in standard streams

There is no automatic association of Language Environment® ddnames SYSTERM, SYSERR, SYSPRINT with the stderr function. In batch processes, you must use command line redirection of the type 1>&2 if you want stderr and stdout to share a device.

In C/370™ V2, you could override the destination of error messages by redirecting stderr. The destination of all Language Environment messages is determined by the MSGFILE runtime option. See the topic on the MSGFILE runtime option in the z/OS Language Environment Programming Guide for more information.
