Question

Hi,
I am having problems executing this program using events. I think it is a simple problem but am not able to solve it.
REPORT  Z_KMADHUR_PROGRAM5.

        call_service_number exporting value(e_servicenumber) type i,
        call_service_type exporting value(e_servicetype) type i.

      create object o_passenger_1 exporting i_seatnumber = 11.
      create object o_passenger_2 exporting i_seatnumber = 17.
      create object o_passenger_3 exporting i_seatnumber = 21.

               exporting i_id = 'purser',
               o_stewardess
               exporting i_id = 'stewardess',
set handler: o_purser->help_the_pilot for o_pilot,
             o_stewardess->help_a_passenger for all instances,
             o_stewardess->give_service_number for all instances,
             o_stewardess->give_service_type for all instances.
call method: o_pilot->call_flight_attendant,
o_passenger_1->call_for_help,
o_passenger_1->call_service_number.
I am getting an error near the start-of-selection. It says "statement is not acceptable".
If i remove the start-of-selection, it says "unable to interpret object. Incorrect spelling or coma error".
<b>My output should look like:
purser helps pilot
stewardess helps passenger on seat 11 to have 2 foodservice.
stewardess helps passenger on seat 11 to have 2 drinkservice.
stewardess helps passenger on seat 17
stewardess helps passenger on seat 17 to have 1 foodservice.
stewardess helps passenger on seat 17 to have 1 drinkservice.
stewardess helps passenger on seat 21
stewardess helps passenger on seat 21 to have 3 foodservice.
stewardess helps passenger on seat 21 to have 3 drinkservice.
stewardess helps passenger on seat 25
stewardess helps passenger on seat 25 to have 1 foodservice.
stewardess helps passenger on seat 25 to have 1 drinkservice.
stewardess helps passenger on seat 31
stewardess helps passenger on seat 31 to have 2 foodservice.
stewardess helps passenger on seat 31 to have 2 drinkservice.</b>
Thanks in advance..

Hi Madhuri,
Usually such errors happen when you fail to put start-of-selection statement to demarcate the variable declaration and the object creation while dealing with local classes.
It can also happen when you fail to close the class definition or implementation using endclass statement or you fail to put a period (.) after the endclass statement..
Just check in your program for similar cases.Of if you don't mind, can you just post the final, modified source-code so that we can analyse it for errors..

Amit.
