Sending longer messages in line mode TSO/E

If you need to use more than 115 characters in a message or you need to send a message to a user on a different system node, you can use the line mode TRANSMIT command. However, with the TRANSMIT command, you need to specify the receiver's system node in addition to a user ID.

To use the TRANSMIT command to send a message to user ANN at system node NETNY, enter after the READY message:

TRANSMIT netny.ann

An empty edit screen, similar to the following, appears on which you can type a message.

                      DATA FOR NETNY.ANN
00001 Ann,
00002    The meeting scheduled for tomorrow at 1:00 was cancelled.
00003 We're rescheduling it for next Tuesday, same time, same place.
00004    See you there.
00005

⋮

00020
00021
00022
PF3 = FINISHED|   PF7 = BACKWARD   |   PF8 = FORWARD   |   PA1 = ABORT

When you press PF3, the message goes to the user and you see:

0 message and 4 data records sent as 5 records to NETNY.ANN
Transmission occurred on 10/14/1987 at 11:30:48.

To send a message to more than one user, separate ‘system nodes.user IDs’ with commas and enclose them in parentheses.

TRANSMIT (netny.mike,netny.ann,netma.bob)

The message you type on the edit screen then goes to all three users.

Your installation may use various security features that affect the way the TRANSMIT command works. If so, the results of transmitting a message may differ from those described here. z/OS TSO/E User's Guide explains the differences you can expect.

Exercise
With the TRANSMIT command, send a message of your choice to another user. Then send it to more than one user.

A quicker way to specify a receiver is to set up a NAMES data set with nickname equivalents for commonly used ‘system nodes.user IDs’. To find out how to set up and use a NAMES data set, see z/OS TSO/E User's Guide.
