7.64 MESSAGE (Display message on console like VM)

7.64.1 Function

The MESSAGE command is actually a VM CP command. It is used to transmit message text to the virtual console of other active users.

However, some programmers also use this command as a simplified way to display messages on the own virtual machine console by using "MESSAGE * <message text>". One program that uses this is the

IBM "System z" port of Solaris which is only capable of running under z/VM.

So basically, all the MESSAGE command does is to display a message on the Hercules console with VM like headers. Therefore the MESSAGE command is not really intended to be used directly from the Hercules console as shown in the example below, although it does not hurt doing so.

MSG is the same as MESSAGE. See also the MSG and MSGNOH commands in this manual.
