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 number
where number can be a zero or non-zero value.
While the default value is "0", (off, false, no) this configuration variable can also take values of the value of "On" (yes, true).
