When A_MSSQL_NO_23_ON_START is set to TRUE, START does not detect whether records matching the search criteria 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. The default value is FALSE.
Example
A_MSSQL_NO_23_ON_START TRUE
