Producing messages

You can get the system to produce a message by issuing a macro in any program or by asking an operator to enter a command. The macros and command are:

• LOG operator command to write a message to the SYSLOG and OPERLOG
• WTL macro to write a message to the SYSLOG and OPERLOG
  Note: Use WTO specifying MCSFLAG=HRDCPY instead of using WTL, which provides additional information with the WTO message that is not with the WTL message.
• WTO macro to write a message to the operator
• WTOR macro to write a message to the operator and request a reply

Use the following for related activities:

• DOM macro to delete an operator message or group of messages from the display screen of a console
• REPLY operator command to answer a message
• WRITELOG operator command to start, stop, or print the SYSLOG and to change the output class for the SYSLOG

For additional information, see the following resources:

• See z/OS MVS Programming: Authorized Assembler Services Reference ALE-DYN for DOM and z/OS MVS Programming: Authorized Assembler Services Reference SET-WTO for the WTO, WTOR, and WTL macros.
• See z/OS MVS System Commands for the LOG, REPLY, and WRITELOG commands.
