Syntax to call one method with the returning of another method?

[RyanK]

I'd like to call one method with the results of another method and I keep getting the error 'The field XYZ(' is unknown but there is a field with a similar name' Error.

Consider the simple example below:

CLASS ZLCL_HELPER DEFINITION.

PUBLIC SECTION.

CLASS-METHODS emit IMPORTING text TYPE string.

CLASS-METHODS get_text RETURNING text TYPE string.

ENDCLASS.

I'd like to call emit with value of get_text without declaring a string type object in the caller such as:

START-OF-SELECTION.

DATA: text TYPE string.

text = zlcl_helper=>get_text( ).

zlcl_helper=>emit( text ).

I'd rather do something like:

START-OF-SELECTION.

zlcl_helper=>emit( zlcl_helper=>get_text( ) ).

Is there a way to do this?

Thanks,

Hi Ryan,

you got it almost right....try using following syntax...

zlcl_helper=>emit( text = zlcl_helper=>get_text( ) ).

I still have the field "GET_TEXT(" is unknown problem. Here is the code that I tried. Am I missing something else?

CLASS zlcl_helper DEFINITION.

PUBLIC SECTION.

CLASS-METHODS emit IMPORTING text TYPE string.

CLASS-METHODS get_text RETURNING VALUE(text) TYPE string.

ENDCLASS.

CLASS zlcl_helper IMPLEMENTATION.

METHOD get_text.

text = 'xyz'.

ENDMETHOD.

METHOD emit.

WRITE text.

ENDMETHOD.

ENDCLASS.

START-OF-SELECTION.

zlcl_helper=>emit( text = zlcl_helper=>get_text( ) ).

You can't nest method calls. You have to split it into two.

some_text = zlcl_helper=>get_text( ). 
zlcl_helper=>emit( text = some_text( ).

Hi Ryan,

The syntax requires a space after the opening bracket '(' and before the closing one ')'....thats it..

rest the code is fine....works for me..
