Comments:
This option (in conjunction with CXML-OPEN-FILE) lets you parse individual records of a file, as opposed to parsing the entire file all at once. This operation parses the next record in the element of the specified handle. No data is returned, but now more data is available for retrieval by other op-codes. Return-code is 0 on error (including end-of-file) or non-zero if everything worked.
This option is more efficient than parsing entire files, but you must remember to parse the record before you try to retrieve its elements.
