How CICS builds the list of autoinstall models
If CICS finds an MTS model name (and the model is defined to CICS and is
compatible with the VTAM information describing the resource), CICS puts the
model name into the model name list (Autinstmodelname_1), and also into the
model name field (Modelname) in the selection list addressed by fullword 4 of the
parameter list.
If CICS is unable to find an MTS model name in the MTS Control Vector, or the
named model does not exist or is invalid, it builds the list of autoinstall models by
selecting from the complete list of terminal models those models that are
compatible with the VTAM information describing the resource. The complete list of
autoinstall models available to CICS at any time comprises all the definitions with
AUTINSTMODEL(YES) and AUTINSTMODEL(ONLY) that have been installed, both
by the GRPLIST at a CICS initial or cold start, and by INSTALL GROUP commands
issued by CEDA. The
CICS Resource Definition Guide describes the definition of
models.
Table 40 on page 768 gives you the information to work out which model types
could be included in the subset of models passed to the autoinstall control program
when a particular terminal attempts to install. The subset is determined by the
