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).

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_classnumber
 
 TYPE KLAH-CLINT ,
ld_classname
 
 TYPE KLAH-CLASS ,
ld_description
 
 TYPE SWOR-KSCHL ,
ld_classtype
 
 TYPE KLAH-KLART ,
ld_language
 
 TYPE SWOR-SPRAS ,
ld_language
 
 TYPE SWOR-SPRAS ,
ld_buffer
 
 TYPE SY-BATCH ,
ld_with_description
 
 TYPE SY-BATCH .



SELECT single CLASS 
  FROM KLAH 
  INTO ld_classname.


SELECT single KLART 
  FROM KLAH 
  INTO ld_classtype.


SELECT single SPRAS 
  FROM SWOR 
  INTO ld_language.

ld_buffer = 'some text here'.
