* TIMER ON enables event trapping of an [[ON TIMER (n)]] statement. While enabled, a check is made after every code statement to see if the specified time has elapsed and the ON TIMER [[GOSUB]] (or [[SUB]] in QB64) procedure is executed.
* TIMER STOP disables timer event trapping. When an event occurs while stopped, it is remembered. If timer events are turned back on later, any remembered events are immediately executed.
* TIMER OFF turns timer event trapping completely off and no subsequent events are remembered.
* Get a TIMER number from [[_FREETIMER]] ONLY except when the base timer(no number or 0) is used. Use specific variables or an array to hold each event number value for later reference.
* If the TIMER number is omitted or 0, the TIMER used is the base timer.
* Specific TIMER events can be enabled, suspended, turned off or freed using [[TIMER (statement)|TIMER(n)]] ON, STOP, OFF or FREE.
