timer = interval
If you have designated a timer-event handling routine (using the
on timer statement), the
timer statement alters the interval at which timer events occur. If timer events have not yet been initiated (because your
on timer statement specified an interval of zero), the
timer statement also initiates timer events.
interval parameter is greater than zero, it specifies the interval in seconds. If
interval is less than zero, then
abs(interval) specifies the interval in ticks (a tick is approximately 1/60 second). Setting
interval to zero disables the timer. Fractional values of
interval are acceptable.
Timer firings are not queued; they are lost if your application does not handle events for times greater than the
