ABAP code example for Function Module LISTSYMBOL_CHECK

The ABAP code below is a full code listing to execute function module LISTSYMBOL_CHECK including all data declarations. The code uses the latest in-line data DECLARATION SYNTAX but I have included an ABAP code snippet at the end to show how declarations would look using the original method of declaring data variables up front. This will allow you to compare and fully understand the new inline method. Please note some of the newer syntax such as the @DATA is not available until a later 4.70 service pack (SP8).

DATA:
ld_symb_size  
 
 TYPE STRING
.


DATA(ld_symbol_name) = 'some text here'.

DATA(ld_language) = 'Check type of data required'.
.

CALL FUNCTION 'LISTSYMBOL_CHECK'
  EXPORTING
    symbol_name =                ld_symbol_name
*   language =                   ld_language
  IMPORTING
    symb_size =                  ld_symb_size
  EXCEPTIONS
    SYMBOL_NOT_FOUND =           1
    .  "  LISTSYMBOL_CHECK

IF SY-SUBRC EQ 0.

  "Add code for exception here
ENDIF.

ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_symb_size
 
 TYPE STRING ,
ld_symbol_name
 
 TYPE STRING ,
ld_language
 
 TYPE SY-LANGU .


ld_symbol_name = 'some text here'.
ld_language = 'Check type of data required'.
