MPE/iX NOTES
The wall command is currently implemented as a call to the MPE/iX CI command TELL to
send messages to all users. As a result, users receive each line of the message prefixed with
the session number and the name of the user who sent the message. If an error occurs while
using TELL to contact a user, the message is displayed on $STDLIST. For more information
on TELL, refer to the MPE/iX Commands Reference Manual.
On
MPE/iX, the end-of-file sequence is :eod followed by ENTER. Typing a subsystem break (-
CTRL-Y) also terminates the message, causing it to be sent.
For more information on how the current MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
