When A_MSSQL_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. While the default value is "Off" (false, no), this configuration variable can also take the value of "On" (true, yes).
Example
A_MSSQL_NO_23_ON_START number
where number can be a zero or non-zero value.
