Section, Line number, Column number; Function function: The file specified (tablename) is empty.
What happened: The table you specified in the function function call was empty. Nothing could be looked up. Section identifies the section of the rule file that contains the errant function call. tablename identifies the empty LOOKUP table.
What to do: Make sure you specify the correct LOOKUP table in the function call. Make sure that the <CONTENT> tag subgroup of the <TABLE> group in the control file did not terminate prematurely. Make sure the string, start, and length parameters are set correctly. A %%RC value of 3 indicates in the rule file that the LOOKUP table was missing or empty.
