ON creates event procedure calls or enables event trapping.
|
|
|
|
|
|
* Set the sub-procedure call for [[KEY(n)]], [[ON COM (n)|COM(n)]], [[PEN]], [[PLAY]], [[STRIG(n)]], [[TIMER]], [[UEVENT]]
|
|
|
|
* To turn on event trapping for [[ON COM (n)]], [[ON KEY (n)]], [[ON PEN]], [[ON PLAY (n)]], [[ON STRIG (n)]], [[ON TIMER (n)]] and [[ON UEVENT]].
|
|
|
|
* In the case of [[ON ERROR]] the trap is also enabled until a subsequent ON ERROR statement.
|
|
* ON procedures should be used only in the main program module and not inside of SUB procedures!
|
|
* If you have used the [[$CHECKING]]:[[OFF]] metacommand, [[$CHECKING]]:'''ON''' will turn on c++ error checking again.
