TSO SEND command

The TSO SEND command can be enhanced with the IKJEESX0 user exit so it can send messages to z/OS® Explorer users. The IKJEESX0 user exit that is provided by z/OS Explorer supports a subset of the normal TSO SEND options.
{SEND | SE} 'message' USER({* | userid [userid …]}) [{NOW | LOGON | SAVE}]
  • The IKJEESX0 user exit is in FEK.SFEKAUTH, unless you used a different high-level qualifier during the SMP/E install of z/OS Explorer.
  • The only required configuration is making the exit available to TSO using STEPLIB, LINKLIST, or LPA.
  • The message is delivered to the specified users at all active RSE daemons.
  • The single quotation mark (') character is not allowed in the message text as the message must be enclosed in single quotation marks.
  • The maximum length of the SEND command including the options and message text is limited to 320 bytes.
  • Keyword NOW is used to send a message to active users only. This is the default.
  • Keyword LOGON is used to send a message to active users, and to store the message for disconnected users, who will receive the message upon next logon.
  • Keyword SAVE is used to send a message to disconnected users only, who will receive the message upon next logon.
Note: When you are using a Legacy ISPF Gateway to provide the TSO command line in the z/OS Explorer client, you can add FEK.SFEKAUTH to STEPLIB in rse.env to provide the IKJEESX0 user exit to TSO. You must use LINKLIST or update the user's TSO logon procedure when you are using an Interactive ISPF Gateway for the TSO command line. For a description of these system services, see (Optional) Interactive ISPF Gateway.
