Paul You should know that there are 3 flavours of SSCP LOGOFF which may be used to end your TSO - or any SNA application - sessions. And the operator's slumber need never be disturbed.
The 3 flavours are as follows as implemented with the TYPE operand of the USS (meaning VTAM Unformatted System Services) LOGOFF command: - TYPE(COND) which allows the application program to take whatever action it likes - TYPE(UNCOND) which requires the application program to terminate the session - TYPE(FORCE) which causes the session to be terminated by VTAM The intention of these last two options is to permit TYPE(UNCOND) to be tried first - since this allows a more orderly session termination - followed by TYPE(FORCE) if it is evident that the application - at least in respect of this session - is broken. SSCP LOGOFF may be used to "disconnect" a TSO session. The session can be "reconnected" at the same point using the RECONNECT option if logon is within the RECONLIM time. LOGOFF TYPE(COND) must be used. I used to tell my students that this can be very useful if, deep down in an ISPF dialog, it is discovered that the 3270 terminal device does not support graphics. I expect this is an issue which does not arise with the all-singing all-dancing 3270 emulators of today. Unfortunately - in my opinion, which I have aired before either here or on IBMTCP-L - you don't get the 3 flavours with TN3270E (RFC 1647). The SSCP LOGOFF function describes only the use of the LOGOFF command with no operands. It is up to the TN3270E server to decide, in effect, which of the three flavours to implement using the VTAM API for a secondary LU - since the options correspond respectively to TERMSESS OPTCD=COND, UNCOND and UNBIND. In the extremely unlikely event you want to research this further be aware - that TERMSESS TYPE=COND maps to the CTERM "type orderly", LOSTERM "unconditional" and corresponds to LOGOFF TYPE(COND), - that TERMSESS TYPE=UNCOND maps to the CTERM "type forced", LOSTERM "forced" and corresponds to LOGOFF TYPE(UNCOND) and - that TERMSESS TYPE=UNBIND corresponds to LOGOFF TYPE(FORCE) A terminological thicket of confusion!
