You can create a local class within a report program in SE38.



report zrich_0001.

*---------------------------------------------------------------------*
*       CLASS lcl_a DEFINITION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
class lcl_a definition.

  public section.
    methods: constructor,
             a_method.

endclass.

*---------------------------------------------------------------------*
*       CLASS lcl_a IMPLEMENTATION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
class lcl_a implementation.

  method constructor.
    write:/ 'A constructor'.
  endmethod.

  method a_method.
    write:/ 'A method of the class lCL_A has been fired'.
  endmethod.

endclass.



data: o_cla type ref to lcl_a.


start-of-selection.

  create object o_cla.
  call method o_cla->a_method( ).

If your class was created in class builder in SE24, then you will need to instanitate your object, meaning use th create object statement, and then call your method, like in the "START-OF-SELECTION in the above program.

Rich,

I don't understand why the write statement in the 'Constructor' method produced output in the list. Unlike the 'A_method' method, it wasn't explicitly called within the Start-of-selection event.

I'm up to page 100 in the new 'ABAP OBJECTS' book and I'm quite confused by different examples I see in different places.

Thanks

Bruce

The constructor method is called by the "create object" within the start-of-selection. This fires off the constructor method.

Good luck.

Thanks Brian. As I was drifting off to sleep last night I thought that "Constructor" must be a reserved word. I appreciate your answer. Unfortunately, since I didn't start this message, I can't award you any points.

Thanks again

Bruce
