As Peter points out, the
standard: "$(cons)"
in the ACD is only for preventing the program to prompt for symbcons when run 
interactively in a text terminal or presenting the symbcons box in a GUI 
(provided that the GUI handles the ACD correctly). But the program can still 
obtain a value for probcons. So, inside the C code of the program we need :

if (ajAcdGetBool("cons") {
   myconsensussymbolstring = ajAcdGetString("symbcons");
   HERE SOME CODE THAT COMPUTES THE CONSENSUS
} else {
   OPTIONALLY SOMETHING TO DO IF YOU DO NOT WANT A CONSENSUS
}

if you use a toggle instead of a boolean it would be ajAcdGetToggle
