Sorry Nick, this doesn't help much. 
1. Do we not need to define varlist/namelist/anything after syntax
2. How do you put it as macro in the query. Is it going to be
syntax anything, STARTdate(str) ENDdate(str) BROKERid(numeric)   /* anything because the arguments are not varlists 
odbc load, exec("select date(read_date), count(*) from readership where source_id=`BROKER_id' and date(read_date) between '`STARTdate'' and '`ENDdate'' group by date(read_date)")
or 
odbc load, exec("select date(read_date), count(*) from readership where source_id=`anything list' and date(read_date) between '`anything list'' and '`anything list'' group by date(read_date)")
