Shell redirection and automatic conversion

In the z/OS® shell or the tcsh shell, when the shell is redirecting the standard input (stdin), standard output (stdout), or standard error (stderr), the default behavior is no automatic conversion of tagged files and no tagging of files created by the redirection. However, shell variables can be used to control the automatic conversion. For more information about shell redirection and automatic conversion, see Shell variables (shell variables for automatic conversion) and tcsh shell and environment variables (using tcsh shell variables to control automatic conversion).

You can also use shell variables for commands in a pipeline. For example, they can be used to tag the standard output of each command that is writing to a pipeline or to tag the standard input of each command that is reading from a pipeline.
