Examples

CALL ttWarnOnLowMemory(1, 0);

Enables low memory warnings for the permanent data partition only.

Note:

This procedure is connection specific, and so you must issue it for each connection upon which warnings are desired. Also, the current setting does not persist to subsequent connections.
