I thought about these two flags last night, in regard to this whole 
issue.  Frankly, I don't understand the difference between FlagResetValues 
and FlagDeletValues.  All the documentation says is:
    * atcFlagDeleteValues = 1 - deletes all previous data from composite 
symbol at the beginning of scan (recommended)
    * atcFlagResetValues = 32 - reset values at the beginning of scan (not 
required if you use atcFlagDeleteValues)
I'm not sure what the difference is between the word "deletes" and "reset" 
above.

On another subject, here's some AFL function (probably buggy) pseudocode 
off the top of my head.

function AssignToComposite(AssignValue, ATCTicker, ATCField, optional:ATCFlag )
{
      //Get value of composite array's field
      CompArrayVal = Foreign(ATCTicker, ATCField);
      //Add the inverse of the value back into the composite array's field 
in order to reset field to zero
      AddToComposite(-CompArrayVal, ATCTicker, ATCField, ATCFlag);
      //Now assign the LocalArray to the composite array's field so that it 
will be statically available at the beginning of the next Explore iteration
      AddToComposite(AssignValue, ATCTicker, ATCField, ATCFlag);
      // return nothing
}

function ResetAllCompositeFields( AssignValue, ATCTicker, optional:ATCFlag )
{
      AssignToComposite(AssignValue, ATCTicker, "O", optional:ATCFlag );
      AssignToComposite(AssignValue, ATCTicker, "H", optional:ATCFlag );
      AssignToComposite(AssignValue, ATCTicker, "L", optional:ATCFlag );
      AssignToComposite(AssignValue, ATCTicker, "C", optional:ATCFlag );
      AssignToComposite(AssignValue, ATCTicker, "I", optional:ATCFlag );
      AssignToComposite(AssignValue, ATCTicker, "V", optional:ATCFlag);
      // return nothing
}
