Internal Additions

Other versions: 7.31 | 7.40 | 7.54

These additions are for internal use only. Do not use them in application programs.


1. ... FROM LOGFILE ID key

2. ... USING subr[(prog)]

Addition 1



Imports data objects from update data records. As key, you have to specify the update key that was assigned by the system (with sequential request number). If the update key specified does not exist in the database table VBDATA, the runtime error IMPORT_UNEXPECTED_END_OF_DATA occurs.

Addition 2

... USING subr[(prog)]


This addition can be specified for IMPORT FROM DATABASE if a table work area dbtab is declared for the relevant database table using TABLES. The TO wa addition is not permitted. The data is not imported from the database table. Instead, the subroutine subr is called. In the subroutine, the first row of a data cluster must be provided in the table work area dbtab as it would be read from the database. The subroutine is then called automatically as often as required until a complete data cluster has been imported, whereby the table work area dbtab has to be filled accordingly at every call.

The subroutine must either be defined in the same program or in a program, prog, specified explicitly. Its name must be prefixed with the name of the database table ("dbtab"). The subroutine must have a USING parameter of type any, which is currently not supplied.


  • FROM DATABASE ... USING is not intended for external use; instead, TO INTERNAL TABLE is used.
  • Specifying an external program prog is the same as the obsolete variant of PERFORM.


Exports a data cluster into an internal table instead of a database table. After that, imports from the internal table

TABLES demo_indx_table. 

DATA demo_indx_tab TYPE TABLE OF demo_indx_table. 

DATA sflight_tab TYPE TABLE OF sflight. 

SELECT * FROM sflight INTO TABLE sflight_tab. 

EXPORT sflight_tab TO DATABASE demo_indx_table(fl) ID 'FLIGHTS' 
       USING demo_indx_table_export.

IMPORT sflight_tab FROM DATABASE demo_indx_table(fl) ID 'FLIGHTS' 
       USING demo_indx_table_import. 


FORM demo_indx_table_export USING foo. 
  APPEND demo_indx_table TO demo_indx_tab. 

FORM demo_indx_table_import USING foo. 
  READ TABLE demo_indx_tab INTO demo_indx_table 
                           WITH KEY srtf2 = demo_indx_table-srtf2. 
  demo_indx_table-srtf2 = demo_indx_table-srtf2 + 1.
