no_elminfo

This field has its origins in the DUPLICATE action: if this field is set, hsolve does not store some information about the model because it is already present in the hsolve element that was duplicated. A side effect of this is that this field can also be used without using DUPLICATE: this saves some memory, but the command findsolvefield and the actions HPUT and HGET fail to work. When you create the right incoming and outgoing messages before the SETUP, this is no problem. Nevertheless the no_elminfo field was used in times where computers were shipped with small memories, but in the current era it has become obsolete.
