You need to consider the difference between the 'ID' of a variable or column, and the specific 'instance' (index) of the variable of column spot in the row of a table. And the full OID that you see/use is composed of the base value, appended with the index info. When its a scalar variable, the instance is always zero. When its in a table, its what ever the specific instance of all the 'index' components are. (normally indexes into table (rows) are never zero) Note that tables can have multiple indexes, and non-interger indexes too. So in your case, the zero tells us this variable is a simple 'one-of' variable, and not a row/column slot in a table. Hope this clears it up.
