ETO= parameter for procedures

Use the ETO= parameter in procedure to specify whether IMS Extended Terminal Option (IMS ETO) is enabled. Valid values are N, M, and Y. The default is N.

N
Specifies that terminals that are not defined to IMS have session initiation attempts rejected. Logon user data is not supported for static terminals; any user data provided at logon time is ignored.
M
Specifies that terminals that are not defined to IMS have session establishment attempts rejected. Logon user data is supported for static terminals; any user data provided at logon time allows automatic sign on to occur during session initiation.
Y
Specifies that terminals that are not defined through the system definition process can establish sessions with IMS if the following conditions are true:
  • The terminal type is supported by IMS for dynamic allocation.
  • A default logon descriptor (provided either by IMS or by you) has sufficient information to create the control blocks necessary to accept the session request.
  • The IMS ETO is installed.
