MPE/iX NOTES

The current

MPE/iX implementation of the write uses the MPE/iX CI TELL command to send

messages to other users. As a result, the user to whom you are sending receives each line of

the message preﬁxed with the session number and your user name. (This does not occur when

you send a message to yourself because, in that case, the message simply appears on your

screen.) If an error occurs while using TELL to contact a user, the message appears on

$STDLIST. For example, write cannot determine if it has permission to write to a user be-

fore attempting to do it. It calls TELL to write the message and if TELL cannot do so, TELL

generates an error message. For more information on TELL, refer to the MPE/iX Commands

Reference Manual.

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.
