HPU : external file support for IN predicate

our customer wants to migrate from a competitor's product to IBM HPU. This product supports the following syntax to read a list of arguments for the SQL -  WHERE IN predicate from a flat file. The syntax is as follows:

SELECT * FROM creator.tbname
WHERE columnName IN (FILE(ddname) )

ddname points to a file in the JCL. The file contains many records with arguments to select a subset of rows from the table. The records in the file are in unload format, not comma-separated and strings have no string-delimiters. The checking of the list is done with a quick search algorithm.
