why this abap call dialog statement is valid?

Question

I found an abap statement like this

CALL DIALOG 'RF_TABELLE_030'
    EXPORTING T020-AKTYP MSMOD IMP-GRUPP FROM 'BIL'
    IMP-KTOSL FROM 'BIL'
    IMPORTING MSGNR TBSPR TDDAT-CCLASS.

I can't find the matching syntax of it from the latest abap keyword document. I guess it might be valid in older abap release(for example, 620), but I can't find the document (the earliest I can find is for 731). please help! many thanks!

You can find the documentation of CALL DIALOG in the Obsolete Calls section. It is a valid (but deprecated) statement.

CALL DIALOG AS ABAP Release 756
