sing a timestamp column is the only way to absolutely ensure modifications made to a row are not overwriting someone else's changes. See the discussion of BROWSE MODE in the Sybase Commands Reference Manual. When it's reading a table that is open for I/O, the Acu4GL for Sybase product uses BROWSE MODE if a timestamp column exists. When the Acu4GL product is creating a table, if the value of A-SYB-ADD-TIMESTAMP is 1, then a timestamp column is included in the table. (Note that your COBOL FD should not include the timestamp column.) While the default value is "Off", this configuration variable can also take values of "Yes," "No," "True," "False," or "On."
Example
A-SYB-ADD-TIMESTAMP 1
