I described this possibility earlier (see my comments #5 and #9 to this bug); many record types explicitly check and so don't call dbGetLink() when plink->type==CONSTANT. Thus for this approach to work will require changes to the record types, and the behavior that results is slightly different than that which the calcout's special() routine gives it (a GUI widget showing the A field won't show the value written to INPA until the record next processes).
