13.2.6.9 LIOCS Console File Definition

The DTFCN has no equivalent in MVS because reading and writing via the console is not handled at the GET/PUT level. MVS provides the WTO macro for writing on the console and the WTOR macro for writing a message and reading a reply. Therefore, you must replace a PUT macro for the console by either a WTO macro to display a message or a WTOR macro for displaying a message and reading a reply.

Do not display messages on the console unless they are necessary. The system writes many messages to the operator, and extra messages could lead to confusion and hinder the performance of the installation.
