In the old days, batch programming was the norm and files were processed sequentially from beginning to end. In order to signal the end of file, programmers would sometimes create a record at the physical end of the file and store the highest permissible value in a key field to mark it as the end-of-file record. In a numeric field, the highest permissible value would be all 9's. Before there were date-type fields, dates were stored in numeric or character fields (which after all is the root of the Y2K problem), so "9/99/99" in a date field could mean "end of file" and could cause a batch program to go to EOJ.

Unless you have any of this sort of old program still in use, it's doubtful whether there will be any problem with Sept. 9, 1999.
