This function can take zero, one, or two parameters.
If passed zero arguments, it fills the data binder with the data in the active resultset's row. Returns no value.
If passed one argument, the argument is the name of the resultset to get the values from the current row. Returns no value.
If passed two arguments, the first argument is the resultset name and the second argument is the key identifying the data object to load. Returns 0 if the data does not exist or 1 if it does exist. The use is True() or False() to conditionally execute scripts based on the return value.
