Description

VTLAPSY is a ten-character resettable User 0 parameter that if set to a non-blank value indicates an APSY subsystem that can be used to provide full-screen login support for IODEV=7 terminals (3270-type).

When an IODEV=7 terminal connects to Model 204, one of four connection states is possible:

  • Terminal connection is the result of a VTAM transfer of control from a different Model 204 online. A zap for SirMods Version 7.7 allows VTAM transfer of control even when RACF is used.
  • Terminal connection request passed user data, and the X'0040' bit of TERMOPT is not set. In this case the user data will be processed as a command at connect time.
  • Terminal connection contains user data, and TERMOPT=X'0040'. In this case the user data will be prefixed with the string "LOGON " and the result will be processed as a command.
  • Terminal connection contains no user data (the typical case).

When an IODEV=7 terminal connects with no user data and VTLAPSY is set to a non-blank value (for example, RESET VTLAPSY VT75LOGIN), the following processing is performed:

  1. The user is "logged in" with a User ID and account matching VT75LOGIN and with X'00' privileges.
  2. The $Sir_Login function is enabled.
  3. VT75LOGIN is entered as a command.
  4. The VTLAPSY subsystem is expected to format a full screen and use $Sir_Login to log the user in.
  5. If command level is reached without a successful $Sir_Login call, or if the VTLAPSY subsystem attempts an APSY transfer without a successful $Sir_Login call, a MSIR.0722 non-terminal message is issued and the terminal is disconnected.
  6. If command level is reached after a successful $Sir_Login, then any AUTOSYS subsystem for the thread will be processed.
  7. Any environmental error in $Sir_Login will result in request cancellation.
    Note: A VTLAPSY subsystem must be configured to not log a user in or out (N settings for Log user into M204 and for Log user out of M204 in the APSY SUBSYSMGMT Operational Parameters screen).

Sample APSY

A sample apsy that can be used with the VTLAPSY parameter is provided by Sirius Software. The code is in the SIRIUS file, beginning with UL/SPF Version 7.7. Programs are VTLN.LOGIN and VTLN.ERROR, and the comments in VTLN.LOGIN explain how to customize the programs for the local environment.
