When A-SYB-NO-23-ON-START is set to a non-zero value, START does not detect whether records actually exist. Because it does not detect the existence of records, it is possible, when using this variable, to do a START without error, and for the next READ NEXT to return END_OF_FILE, contrary to the ANSI standard.
Example
A-SYB-NO-23-ON-START zero or a non-zero number
While the default value is "0", this configuration variable can also take values of "Yes," "No," "True," "False," "On," or "Off."
