-----Original Message----- On an old COBOL system, that was written to run on various hardware/os. They had created "lock" files for all the major files. [snip]
-------------------------------------------------------- The key to this statement is "old". This strategy worked because on many older systems I/O was a blocking, atomic operation. In Unix and Windows you can make the reading and writing of a file a blocking operation, but without special options on the open the I/O won't be atomic, which negates the effectiveness of the strategy. ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
