Omitting retrieve values on a command

I have created a "retrieve" command as a front end to some values in a file. Is there a way to shield existing programs from a change to the command? Normally it's easy to add parms to a command without affecting existing programs - as long as the keywords used in those programs still exist. But on a retrieve type command, if I add a parm then the pointer has nowhere to go!

Is there an elegant way to get around this limitation or do I have to go into all the programs, add the parms and associated variables and recompile? TIA.
