EVENT action
Function
Synchronous/asynchronous starting of a subevent.
Declaration
| Blok kódu | ||||
|---|---|---|---|---|
| ||||
EVENT eventIdent [(pubLoc1=param1, pubLoc2=param2, ... , pubLoc10=param10)] [ASYNC] |
Parameters
| eventIdent | in | Identifier of a Event type object. |
| pubLoc1, pubLoc2, ..., pubLoc10 | in | Local variables of PUBLIC type in the called event, the specified parameters will be assigned to. |
| param1, param2, ..., param10 | in | Local variables - their values will be assigned to the local variables of PUBLIC type. |
Description
Before the subevent starts there are automatically filled:
- the values of PUBLIC local variables.
- the predefined variables _FROM_HIP, _HIP_PAR_STR, _HIP_USER_DESC according to the script called.
Without the key word keyword ASYNC, the subscript is to be started synchronously. The action EVENT is terminated after the subevent termination. Values of PUBLIC local variables are to be assigned to the called event (IN OUT parameters in principle). If the called event is terminated by an error, the calling event is not terminated and continues in the execution of the next action.
For asynchronous calling an event (the key word keyword ASYNC), the calling event doesn't wait for the termination of the running event.
When you are using local variables of the RECORD type, it is necessary that the types of the variables must be the same in the called and calling events, in regard to the NOALIAS attribute.
